Hagia Sophia of Theodusius was burned down in the fire of Nika Revolt in 532 A.D. during the reign of Justinian. The same year Justinian ordered to build a new basilica the one we can see today, and only 5 years later, 537 A.D. it was opened to the public. Hagia Sophia, the legacy of both Christian and Muslim culture, was opened for visits as a museum according to the order of Ataturk in 1935. See here: en.wikipedia.org/wiki/Hagia_Sophia. Also known as Aya Sofia. (Hits: 11017)
