What lies beneath

This is a photo taken inside the Basillica Cistern in the historical village of Sultanahmet.  Its the largest of several hundered cisterns that lie beneath the city of Istanbul and its pretty amazing to visit.  It was built in the 6th century!  Before then a Basillica stood in its place, built in the 3rd century and that is where it gets its name from.  The feeling is eery but has the potential to take you right back in time.  Highly recommended.
