Aya Sofya (Haghia Sophia) was built by Justinian in 537. For almost a thousand years it was the largest church in the world. After Constantinople fell to the Turks it was converted to a mosque and later a museum. Its mammoth dome rises 184 feet into the air-the Statue of Liberty could easily fit inside. Many of it's famed gold mosaics can still be seen.
