Hagia Sophia

The Hagia Sophia (meaning Holy Wisdom) was constructed in 537AD by the Byzantium Empire, apparent through its architecture as an Eastern Orthodox cathedral. The entire catherdral was completed in 5 years, with no more than simple scaffolding. It remained in it's purpose until 1453AD when the Ottomans captured Constantinople and converted it into a mosque. It remained a mosque until 1935AD when it was completely secularised and made a museum, which it is now. This building is truly an artistic and architectural world wonder.
