Database: Cistern of Mocius

Built on Seventh Hill by the Roman Emperor Anastasius in the sixth century, the Cistern of Mocius was fairly large by Constantinople's standards, and notable for the fact that it is one of the few above ground cisterns still visible today - just behind the tennis courts and park benches. Honestly, if you look closely, you can still see some sections of its outer walls... beneath all the grass and dirt.
