The Basilica Cistern

It was built during the reign of Justinian I (527-565) to supply water to the palaces in the vicinity. Its 336 columns are arranged in 12 rows of 28 each. The Cistern measures 140 by 70 meters. The columns are topped with capitals, some of them plain, but most in corinthian style. The water level in the Cistern changed from season to season. The water was distributed through the pipes at different levels in the eastern wall.

The ground was cleared during the major restoration in 1987, and when over one meter of mud was removed, the original brick pavement and two marble Medusa heads at the base of two the columns were revealed. The walkway that was constructed at that time enables visitors to walk around the Cistern.

Circumcision Room - Summer Pavilion

"This summer pavilion was built by Sultan İbrahim in 1640. As this place was used for the circumcision ceremonies of the crown princes, it is also called Circumcision Room.

The walls are covered with the rare specimens of Ottoman tiles. The most important of these are the blue and white tile panels influenced by the Far-Eastern ceramics on the chamber facade dated 1529."
