December 27, 537 - Hagia Sophia Consecrated

The greatest basilica of the Greek Orthodox Church was the Hagia Sophia built in then-Constantinople. It was consecrated on December 27, 537 AD and served as the home of the patriarchs of the church. In the mid 1400s it was taken over by Turks and was a Muslim mosque and is now a museum. This is a picture of the inside that can be seen on tours today.
