Cistern

Roman cistern, view from North (Kadıoğlu, 2021, 308, Figure 137)

Located in the southwest of the city and approximately 350 m south of the Temple of Dionysus, the cistern was built along an east-west axis, in accordance with the topography, and its façade faced the Sanctuary of Dionysus. The structure is rectangular, 47 m long and 6.80 wide, built with rubble masonry and lime mortar, and covered with a barrel vault. The vault of the cistern is preserved only on the eastern part and all the arches on the façade but the 4^th and 5^th were destroyed.

All the inner walls of the cistern were plastered with 10–12 cm thick opus signinum until the springing of the vault, to ensure impermeability. The 3 m deep cistern (calculated until the springing of the vault) could hold at least 542 m³.
