Free Day in Istanbul

Today was our chance to explore some parts of Istanbul, within walking distance of our hotel. The most unexpected of these was the huge underground water cistern. We were certainly not expecting to find a huge underground water cistern, built more like a cathedral than a water tank.

This was actually one of several such cisterns which were designed to store water for the inhabitants of Constantinople.

Fifty-two stone steps descend into the entrance of the cistern. The cistern is surrounded by a firebrick wall with a thickness of 4 metres (13 ft) and coated with a waterproofing mortar. The Basilica Cistern's water came from the Eğrikapı Water Distribution Center in the Belgrade Forest, which lie 19 kilometres (12 mi) north of the city. It traveled through the 971-metre-long (3,186 ft) Valens (Bozdoğan) Aqueduct, and the 115-metre-long (377 ft) Mağlova Aqueduct, which was built by the Emperor Justinian.[1]

The weight of the cistern lies on the columns by means of the cross-shaped vaults and round arches of its roof.

The Basilica Cistern has undergone several restorations since its foundation. The first of the repairs were carried out twice during the Ottoman State in the 18th century during the reign of Ahmed III in 1723 by the architect Muhammad Agha of Kayseri. The second major repair was completed during the 19th century during the reign of Sultan Abdulhamid II (1876–1909). Cracks to masonry and damaged columns were repaired in 1968, with additional restoration in 1985 by the Istanbul Metropolitan Museum. During the 1985 restoration, 50,000 tons of mud were removed from the cisterns, and platforms built throughout to replace the boats once used to tour the cistern.

The cistern was opened to the public in its current condition on 9 September 1987. In May 1994, the cistern underwent additional cleaning.

Tomorrow we catch a short domestic flight to Nevsehire.Read more
