HAGIA SOPHIA MUSEUM
Hagia Sophia, which is considered as one of the eight wonders of the world, also occupies a prominent place in the history of art and architecture. It is one of the rare works of this size and age that has survived to our day. The church (called Ayasofya in Turkish) is erroneously known as Saint Sophia in the west. The basilica was not dedicated to a saint named Sophia, but to Divine Wisdom. St. Sophia has been an inspiration for Ottoman mosques thought in idea, and is reviewed as a product of east-west synthesis. St. Sophia served for 916 years as church and 481 years as mosque since its year of construction. Hagia Sophia was turned into a museum in 1935.
