Cistern with near square plan, approximately 16 m × 11 m, renovated as a luxury restaurant. Has two sets of six columns with cross vaults. Bricks are 204 cm and 4-6 cm thickness. The corners are rounded against internal water pressure. On the southwest, there are now four later opened windows, as well as a kitchen on the northwest corner (fireplace added to north wall) (Altuğ, 2013, p. 190).
Today, it is claimed that the cistern is 1500 years old. This would place the construction roughly in the sixth century(?)
The cistern could originally have been potentially supplied by the Hadrian line (Crow et al., 2008, p. 117).
