Hagia Sophia

I visited the St. Hagia Sophia yesterday. It was built between 532-537AD. This was the seat of the Greek Orthodox Patriach for over a thousand years. Because of its size, compared to other churches of the time, it was named Hagia Sophia, which is Greek for "Holy Wisdom", refering to the second person of the holy trinity. This is a massive building with a dome supported by 4 piers. Originally, the chuch's interior was covered with thousands of mosaics, which can be seen in my pictures. However, after the Muslim invasion of 1453AD it was converted to a mosque and the mosaics were painted over. It is now a museum.
