The Hagia (Holy) Sophia (Wisdom) is a stunning domed building built as a Greek Orthodox cathedral in 537 when Istanbul, then called Constantinople, Â was the capital of the Eastern Roman Empire(also known as the Byzantine Empire). Â Between 1204 and 1261 it was a Roman Catholic cathedral. Â Following the conquering of the Empire by the Ottomans in 1453, the Hagia Sofia became a mosque. Â In 1931 it was closed and then converted into a museum, which it is still. Â The minarets and round domes give it an Islamic setting, and some of the interior maintains that influence as well. Â Nonetheless it is an impressive structure, notably the dome, and for 1000 years it was the largest cathedral in the world, replaced in 1520 by the Cathedral in Seville.
