The Interior of the Hagia Sophia Museum in Istanbul, Turkey

The Hagia Sophia, whose name means “Holy Wisdom,” is also called the Church of the Holy Wisdom or the Church of the Divine Wisdom. The structure was built originally as a Christian church, converted into a mosque and today, a museum. The museum was originally built as a cathedral in Constantinople (present-day Istanbul, Turkey) in the sixth century A.D. Its structure is based on a central plan, consisting of two floors centered on a giant nave with a great dome ceiling, along with smaller domes. When The Byzantine era ended in 1453 and Constantinople fell, the body of the original church was surrounded by later additions, including minarets built by the Ottoman Turks. Today, the Hagia Sophia is one of the most visited museums in the world.
