Hagia Sophia

Hagia Sophia is a former Orthodox patriarchal basilica (church), later a mosque, and now a museum in Istanbul, Turkey. From the date of its dedication in 360 until 1453, it served as an Eastern Orthodox cathedral and seat of the Patriarchate of Constantinople, except between 1204 and 1261, when it was converted to a Roman Catholic cathedral under the Latin Empire. The building was a mosque from 29 May 1453 until 1931, when it was secularized. It was opened as a museum on 1 February 1935.

Basilica Cistern

The Basilica Cistern (Turkish: Yerebatan Sarayi – "Sunken Palace", or Yerebatan Sarnici – "Sunken Cistern"), is the largest of several hundred ancient cisterns that lie beneath the city of Istanbul, Turkey. The cistern, located 150m southwest of the Hagia Sophia, was built in the 6th century during the reign of Byzantine Emperor Justinian I.

I’ve had the chance to use a tripod to take this shot, before being reprimanded by a guard because it was not allowed. It is an HDR from 3 shots, tone mapped using Photomatix.
