Cross section of Hagia Sophia in Istanbul (historically Constantinople). The Greek name Hagia Sophia means "Holy Wisdom." It is known as Ayasofya in Turkish.
<p>The building was originally constructed as a church between A.D. 532 and 537 on the orders of the Byzantine Emperor Justinian I. In 1453, Constantinople was conquered by the Ottoman Empire under Mehmed the Conqueror, who ordered the building be converted into a mosque. It was closed in 1931 and reopened as a museum in 1935. This important milestone in the history of architecture was the world's largest cathedral for nearly a thousand years. It also greatly influenced the design of Ottoman mosques, including the nearby Blue Mosque.

"Exterior of the Church of Sta. Sophia at Constantinople. Although the impression conveyed by this church is not so pure and simple as that which the basilicas produce, still its outlines are magnificent and imposing. The exterior displayed a novel divergency from the normal standard. Whist hitherto the antique form of the roof had been preserved, it was now replaced by a totally different one: inasmuch as the vaulting, at least of the domes, was visible from the outside without any screen, or the only covering it had was one of polished metal."
