We had another late start on our second full day in Istanbul. Lucky we don't have a tight schedule for our travels or anything! After loading up on bread at our complimentary hostel breakfast we set out for another full on day of sightseeing in the searing 34 degrees celsius heat.
Our first stop of the day was a visit to the Basilica Cistern or "Yerebatan Sarayı" as it's called in Turkish which means the "Sunken Palace".The Basilica Cistern is a huge cathedral sized ancient cistern that lies beneath Istanbul. Like the Hagia Sofia, it was built in the 6th century AD during the reign of Justinian of the Byzantine Empire. Of course, being a Byzantine construction, it couldn't be just purely functional and is also an astonishing fat of engineering. For the uninitiated, a cistern, at least one of this scale, is a large receptacle with a waterproof lining for holding and storing liquids, usually water. No, it's not just the thing on top of your toilet!
The Basilica Cistern gets it's Byzantine name from its location. It was originally built underneath a basilica (church). According to Wikipedia, some old texts claim that 7000 slaves were used to make the cistern. The Basilica was, and still is, absolutely massive covering an area of 9,800 square meters and with a maximum capacity of 80,000 cubic metres - that's a lot of water. The ceiling of the Basilica Cistern was supported by over 300 marble columns, in various different styles. Some were Ionic, some Doric and a few Corinthian, some plain and a few were engraved. Apparently this was because the builders recycled parts from older Roman ruins.
The Basilica Cistern was cool and echoing and only had a few feet of water lying at the bottom when we were there. The water was filled with strange fat carp-like grey fish.
