hagia sophia

The Church was dedicated to the Wisdom of God, the Logos, the second person of the Holy Trinity, its patronal feast taking place on 25 December, thecommemoration of the Birth of the incarnation of the Logos in Christ.Although sometimes referred to as Sancta Sophia (as though it were named after Saint Sophia), sophia being the phonetic spelling in Latin of the Greek word for wisdom, its full name in Greek is Ναός τῆς Ἁγίας τοῦ Θεοῦ Σοφίας, "Shrine of the Holy Wisdom of God". Famous in particular for its massivedome, it is considered the epitome of Byzantine architecture and is said to have "changed the history of architecture." It remained the world's largest cathedral for nearly a thousand years, until Seville Cathedral was completed in 1520. The current building was originally constructed as a church between 532 and 537 on the orders of the Byzantine Emperor Justinian and was the third Church of the Holy Wisdom to occupy the site, the previous two having both been destroyed by rioters. It was designed by the Greek scientists Isidore of Miletus, a physicist, and Anthemius of Tralles, a mathematician.

The church contained a large collection of holy relics and featured, among other things, a 15-metre (49 ft) silver iconostasis. The focal point of the Eastern Orthodox Church for nearly one thousand years, the building witnessed theexcommunication of Patriarch Michael I Cerularius on the part of Pope Leo IX in 1054, an act which is commonly considered the start of the Great Schism.

In 1453, Constantinople was conquered by the Ottoman Turks under SultanMehmed II, who ordered this main church of the Orthodox Christianity converted into a mosque. By this point, the Church had fallen into a state of disrepair. Nevertheless, the Christian cathedral made a strong impression on the new Ottoman rulers and they decided to convert it into a mosque. The bells, altar, iconostasis, and sacrificial vessels and other relics were removed and the mosaics depicting Jesus, his Mother Mary, Christian saints and angels were also removed or plastered over. Islamic features – such as the mihrab,minbar, and four minarets – were added. It remained a mosque until 1931 when it was closed to the public for four years. It was re-opened in 1935 as a museum by the Republic of Turkey.

From its initial conversion until the construction of the nearby larger Sultan Ahmed Mosque (Blue Mosque of Istanbul) in 1616, it was the principal mosque of Istanbul. The Hagia Sophia served as inspiration for many other Ottoman mosques, such as the Blue Mosque, theŞehzade Mosque, the Süleymaniye Mosque, the Rüstem Pasha Mosque and the Kılıç Ali Paşa Mosque.

sidney opera house

The Sydney Opera House is a multi-venue performing arts centre in Sydney,New South Wales, Australia. Situated on Bennelong Point in Sydney Harbour, close to the Sydney Harbour Bridge, the facility is adjacent to the Sydney central business district and the Royal Botanic Gardens, between Sydney andFarm Coves.

Designed by Danish architect Jørn Utzon, the facility formally opened on 20 October 1973 after a gestation beginning with Utzon's 1957 selection as winner of an international design competition. The NSW Government, led byPremier Joseph Cahill, authorised work to begin in 1958, with Utzon directing construction. The government's decision to build Utzon's design is often overshadowed by circumstances that followed, including cost and scheduling overruns as well as the architect's ultimate resignation.

Though its name suggests a single venue, the project comprises multiple performance venues which together are among the busiest performing arts centres in the world — hosting over 1,500 performances each year attended by some 1.2 million people. The venues produce and present a wide range of in-house productions and accommodate numerous performing arts companies, including four key resident companies: Opera Australia, The Australian Ballet, the Sydney Theatre Company and the Sydney Symphony Orchestra. As one of the most popular visitor attractions in Australia, more than seven million people visit the site each year, with 300,000 people participating annually in a guided tour of the facility.

Identified as one of the 20th century's most distinctive buildings and one of the most famous performing arts centres in the world, the facility is managed by the Sydney Opera House Trust, under the auspices of the New South Wales Ministry of the Arts.

The Sydney Opera House became a UNESCO World Heritage Site on 28 June 2007.

moai

 Nearly half are still at Rano Raraku, the main moai quarry, but hundreds were transported from there and set on stone platforms called ahu around the island's perimeter. Almost all moai have overly large heads three-eighths the size of the whole statue. The moai are chiefly the living faces (aringa ora) of deified ancestors (aringa ora ata tepuna). The statues still gazed inland across their clan lands when Europeans first visited the island, but most were cast down during later conflicts between clans.

The production and transportation of the 887 statues are considered remarkable creative and physical feats. The tallest moai erected, called Paro, was almost 10 metres (33 ft) high and weighed 82 tons;the heaviest erected was a shorter but squatter moai at Ahu Tongariki, weighing 86 tons; and one unfinished sculpture, if completed, would have been approximately 21 metres (69 ft) tall with a weight of about 270 tons. The islanders themselves tore down the standing moai after their civilization broke down.

eiffel tower

 It was named after the engineerGustave Eiffel, whose company designed and built the tower. Erected in 1889 as the entrance arch to the 1889 World's Fair, it was initially criticised by some of France's leading artists and intellectuals for its design, but has become both a global cultural icon of France and one of the most recognizable structures in the world.^[1] The tower is the tallest structure in Paris and the most-visited paid monument in the world; 6.98 million people ascended it in 2011.^[2] The tower received its 250 millionth visitor in 2010.

The tower is 324 metres (1,063 ft) tall, about the same height as an 81-storey building. During its construction, the Eiffel Tower surpassed the Washington Monument to assume the title of the tallest man-made structure in the world, a title it held for 41 years, until the Chrysler Building in New York City was built in 1930. Because of the addition of the aerial atop the Eiffel Tower in 1957, it is now taller than the Chrysler Building by 5.2 metres (17 ft). Not includingbroadcast aerials, it is the second-tallest structure in France, after the Millau Viaduct.

The tower has three levels for visitors, with restaurants on the first and second. The third level observatory's upper platform is 276 m (906 ft) above the ground,the highest accessible to the public in the European Union. Tickets can be purchased to ascend by stairs or lift (elevator) to the first and second levels. The climb from ground level to the first level is over 300 steps, as is the walk from the first to the second level. Although there are stairs to the third and highest level, these are usually closed to the public and it is generally only accessible by lift.

acropolis

In many parts of the world, acropoleis became the nuclei of large cities of classical antiquity, such as ancient Rome, which in more recent times grew up on the surrounding lower ground, such as modern Rome.

The word acropolis literally means in Greek "upper city," and though associated primarily with the Greek cities Athens, Argos, Thebes, and Corinth (with itsAcrocorinth), may be applied generically to all such citadels, including Rome,Jerusalem, Celtic Bratislava, many in Asia Minor, or even Castle Rock in Edinburgh. An example in Ireland is the Rock of Cashel. Acropolis is also the term used by archaeologists and historians to the urban Castro culturesettlements located in Northwestern Iberian hilltops.

The most famous example is the Acropolis of Athens, which, by reason of its historical associations and the several famous buildings erected upon it (most notably the Parthenon), is known without qualification as the Acropolis. Although originating in the mainland of Greece, use of the acropolis model quickly spread to Greek colonies such as the Dorian Lato on Crete during the Archaic Period.

Because of its classical Hellenistic style, the ruins of Mission San Juan Capistrano's Great Stone Church in California, United States has been called the "American Acropolis".

Other parts of the world developed other names for the high citadel or alcázar, which often reinforced a naturally strong website. In Central Italy, many small rural communes still cluster at the base of a fortified habitation known as La Rocca of the commune.

The term acropolis is also used to describe the central complex of overlapping structures, such as plazas and pyramids, in many Maya cities, including Tikal and Copán.

petra

Established possibly as early as 312 BC as the capital city of the Nabataeans,^[2]it is a symbol of Jordan, as well as Jordan's most-visited tourist attraction.^[3] It lies on the slope of Jebel al-Madhbah (identified by some as the biblical Mount Hor) in a basin among the mountains which form the eastern flank of Arabah(Wadi Araba), the large valley running from the Dead Sea to the Gulf of Aqaba. Petra has been a UNESCO World Heritage Site since 1985.

The site remained unknown to the Western world until 1812, when it was introduced by Swiss explorer Johann Ludwig Burckhardt. It was described as "a rose-red city half as old as time" in a Newdigate Prize-winning poem by John William Burgon. UNESCO has described it as "one of the most precious cultural properties of man's cultural heritage". See: UNESCO Intangible Cultural Heritage Lists. Petra was chosen by the Smithsonian Magazine as one of the "28 Places to See Before You Die".

flavian dinasty

The Flavian dynasty was a Roman Imperial Dynasty, which ruled the Roman Empire between AD 69 and AD 96, encompassing the reigns of Vespasian(69–79), and his two sons Titus (79–81) and Domitian (81–96). The Flavians rose to power during the civil war of 69, known as the Year of the Four Emperors. After Galba and Otho died in quick succession, Vitellius became emperor in mid 69. His claim to the throne was quickly challenged by legionsstationed in the Eastern provinces, who declared their commander Vespasian Emperor in his place. The Second Battle of Bedriacum tilted the balance decisively in favour of the Flavian forces, who entered Rome on December 20. The following day, the Roman Senate officially declared Vespasian emperor of the Roman Empire, thus commencing the Flavian dynasty. Although the dynasty proved to be short-lived, several significant historic, economic and military events took place during their reign.

The reign of Titus was struck by multiple natural disasters, the most severe of which was the eruption of Mount Vesuvius in 79. The surrounding cities ofPompeii and Herculaneum were completely buried under ash and lava. One year later, Rome was struck by fire and a plague. On the military front, the Flavian dynasty witnessed the siege and destruction of Jerusalem by Titus in 70, following the failed Jewish rebellion of 66. Substantial conquests were made in Great Britain under command of Gnaeus Julius Agricola between 77 and 83, while Domitian was unable to procure a decisive victory against KingDecebalus in the war against the Dacians. In addition, the Empire strengthened its border defenses by expanding the fortifications along the Limes Germanicus.

The Flavians initiated economic and cultural reforms. Under Vespasian, new taxes were devised to restore the Empire's finances, while Domitian revalued the Roman coinage by increasing its silver content. A massive building programme was enacted to celebrate the ascent of the Flavian dynasty, leaving multiple enduring landmarks in the city of Rome, the most spectacular of which was the Flavian Amphitheatre, better known as the Colosseum.

Flavian rule came to an end on September 18, 96, when Domitian wasassassinated. He was succeeded by the longtime Flavian supporter and advisor Marcus Cocceius Nerva, who founded the long-lived Nervan-Antonian dynasty.

colosseum

 Built of concreteand stone, it was the largest amphitheatre of the Roman Empire, and is considered one of the greatest works of Roman architecture and engineering. It is the largest amphitheatre in the world.

The Colosseum is situated just east of the Roman Forum. Construction began under the emperor Vespasian in 70 AD, and was completed in 80 AD under his successor and heir Titus. Further modifications were made during the reign of Domitian (81–96). These three emperors are known as the Flavian dynasty, and the amphitheatre was named in Latin for its association with their family name (Flavius).

The Colosseum could hold, it is estimated, between 50,000 and 80,000 spectators, and was used for gladiatorial contests and public spectaclessuch as mock sea battles, animal hunts, executions, re-enactments of famous battles, and dramas based on Classical mythology. The building ceased to be used for entertainment in the early medieval era. It was later reused for such purposes as housing, workshops, quarters for a religious order, a fortress, aquarry, and a Christian shrine.

Although in the 21st century it stays partially ruined because of damage caused by devastating earthquakes and stone-robbers, the Colosseum is aniconic symbol of Imperial Rome. It is one of Rome's most popular tourist attractions and has close connections with the Roman Catholic Church, as each Good Friday the Pope leads a torchlit "Way of the Cross" processionthat starts in the area around the Colosseum.

In 2007 the complex was included among the New7Wonders of the World, following a competition organized by New Open World Corporation (NOWC).

The Colosseum is also depicted on the Italian version of the five-cent euro coin.

ming dynasty

The Ming dynasty, also Empire of the Great Ming, was the ruling dynasty of China for 276 years (1368–1644) following the collapse of theMongol-led Yuan dynasty. The Ming, described by some as "one of the greatest eras of orderly government and social stability in human history,"was the last dynasty in China ruled by ethnic Han Chinese. Although the primary capital of Beijing fell in 1644 to a rebellion led by Li Zicheng (who established the Shun dynasty, soon replaced by the Manchu-led Qing dynasty), regimes loyal to the Ming throne – collectively called the Southern Ming – survived until 1662.

The Hongwu Emperor (ruled 1368–98) attempted to create a society of self-sufficient rural communities ordered in a rigid, immobile system that would guarantee and support a permanent class of soldiers for his dynasty: the empire's standing army exceeded one million troops and the navy's dockyards in Nanjing were the largest in the world. He also took great care breaking the power of the court eunuchs and unrelated magnates,enfeoffing his many sons throughout China and attempting to guide these princes through the Huang Ming Zu Xun, a set of published dynastic instructions. This failed spectacularly when his teenage successor, theJianwen Emperor, attempted to curtail his uncles' power, prompting theJingnan Campaign, an uprising that placed the Prince of Yan upon the throne as the Yongle Emperor in 1402. The Yongle Emperor established Yan as a secondary capital and renamed it Beijing, constructed theForbidden City, and restored the Grand Canal and the primacy of theimperial examinations in official appointments. He rewarded his eunuch supporters and employed them as a counterweight against the Confucianscholar-bureaucrats. One, Zheng He, led seven enormous voyages of exploration into the Indian Ocean as far as Arabia and the coast of Africa.

The rise of new emperors and new factions diminished such extravagances; the capture of the Zhengtong Emperor during the 1449 Tumu Crisis ended them completely. The imperial navy was allowed to fall into disrepair whileforced labor constructed the Liaodong palisade and connected and fortified the Great Wall of China into its modern form. Wide-ranging censuses of the entire empire were conducted decennially, but the desire to avoid labor and taxes and the difficulty of storing and reviewing the enormous archives at Nanjing hampered accurate figures. Estimates for the late-Ming population vary from 160 to 200 million, but necessary revenues were squeezed out of smaller and smaller numbers of farmers as more disappeared from the official records or "donated" their lands to tax-exempt eunuchs or temples.Haijin laws intended to protect the coasts from "Japanese" pirates instead turned many into smugglers and pirates themselves.

By the 16th century, however, the expansion of European trade – albeit restricted to islands near Guangzhou like Macao – spread the Columbian Exchange of crops, plants, and animals into China, introducing chili peppersto Sichuan cuisine and highly productive corn and potatoes, which diminished famines and spurred population growth. The growth ofPortuguese, Spanish, and Dutch trade created new demand for Chinese products and produced a massive influx of Japanese and American silver. This abundance of specie allowed the Ming to finally avoid using paper money, which had sparked hyperinflation during the 1450s. While traditional Confucians opposed such a prominent role for commerce and the newly rich it created, the heterodoxy introduced by Wang Yangming permitted a more accommodating attitude. Zhang Juzheng's initially successful reforms proved devastating when a slowdown in agriculture produced by the Little Ice Agewas met with Japanese and Spanish policies that quickly cut off the supply of silver now necessary for farmers to be able to pay their taxes. Combined with crop failure, floods, and epidemic, the dynasty was considered to have lost the Mandate of Heaven and collapsed before the rebel leader Li Zicheng and a Manchurian invasion.

great wall of china

The Great Wall of China is a series of fortifications made of stone, brick,tamped earth, wood, and other materials, generally built along an east-to-west line across the historical northern borders of China in part to protect the Chinese Empire or its prototypical states against intrusions by various nomadic groups or military incursions by various warlike peoples or forces. Several walls were being built as early as the 7th century BC; these, later joined together and made bigger and stronger, are now collectively referred to as the Great Wall. Especially famous is the wall built between 220–206 BC by the firstEmperor of China, Qin Shi Huang. Little of that wall remains. Since then, the Great Wall has on and off been rebuilt, maintained, and enhanced; the majority of the existing wall is from the Ming Dynasty.

Other purposes of the Great Wall have included border controls, allowing the imposition of duties on goods transported along the Silk Road, regulation or encouragement of trade and the control of immigration and emigration. Furthermore, the defensive characteristics of the Great Wall were enhanced by the construction of watch towers, troop barracks, garrison stations, signaling capabilities through the means of smoke or fire, and the fact that the path of the Great Wall also served as a transportation corridor.

The main Great Wall line stretches from Shanhaiguan in the east, to Lop Lakein the west, along an arc that roughly delineates the southern edge of Inner Mongolia. A comprehensive archaeological survey, using advanced technologies, has concluded that the Ming walls measure 8,850 km (5,500 mi).^[5] This is made up of 6,259 km (3,889 mi) sections of actual wall, 359 km (223 mi) of trenches and 2,232 km (1,387 mi) of natural defensive barriers such as hills and rivers. Another archaeological survey found that the entire wall with all of its branches measure out to be 21,196 km (13,171 mi).

inca civilization

The Andean civilizations made up a loose patchwork of different cultures that developed from the highlands of Colombia to the Atacama Desert. They are mainly based on the cultures of Ancient Peru and some others such as Tiahuanaco. The Inca Empire was the last sovereign political entity that emerged from the Andean civilizations before conquest by Spaniards. Tahuantinsuyo was a patchwork of languages, cultures and peoples. The components of the empire were not all uniformly loyal, nor were the local cultures all fully integrated. For example, the Chimú used money in their commerce, while the Inca empire as a whole had an economy based on exchange and taxation of luxury goods and labor, and it is said that Inca tax collectors would take the head lice of the lame and old as a symbolic tribute. The portions of the Chachapoyathat had been conquered were almost openly hostile to the Inca, and the Inca nobles rejected an offer of refuge in their kingdom after their troubles with the Spanish.

Spanish rule ended or transformed many elements of the Andean civilizations notably influencing religion and architecture.

machu pichu

It is located in the Cusco Region, Urubamba Province, Machupicchu District in Peru.^[4] It is situated on a mountain ridge above the Sacred Valley which is 80 kilometres (50 mi) northwest of Cusco and through which the Urubamba River flows. Most archaeologists believe that Machu Picchu was built as an estate for the Inca emperor Pachacuti (1438–1472). Often mistakenly referred to as the "Lost City of the Incas", it is perhaps the most familiar icon of Inca civilization.

The Incas built the estate around 1450, but abandoned it a century later at the time of the Spanish Conquest. Although known locally, it was unknown to the outside world before being brought to international attention in 1911 by the American historian Hiram Bingham. Since then, Machu Picchu has become an important tourist attraction. Most of the outlying buildings have been reconstructed in order to give tourists a better idea of what the structures originally looked like.^[5] By 1976, thirty percent of Machu Picchu had been restored.^[5] The restoration work continues to this day.^[6]

Since the site was not known to the Spanish during their conquest, it is highly significant as a relatively intact cultural site. Machu Picchu was declared a Peruvian Historical Sanctuary in 1981 and a UNESCO World Heritage Site in 1983.^[3] In 2007, Machu Picchu was voted one of the New Seven Wonders of the World in a worldwide Internet poll.

Machu Picchu was built in the classical Inca style, with polished dry-stone walls. Its three primary structures are the Inti Watana, the Temple of the Sun, and the Room of the Three Windows. These are located in what is known by archaeologists as the Sacred District of Machu Picchu.^{[citation needed]}

Machu Picchu is vulnerable to threats. While natural phenomena like earthquakes and weather systems can play havoc with access, the site also suffers from the pressures of too many tourists. In addition, preservation of the area's cultural and archaeological heritage is an ongoing concern.
