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.
