Reservoir of Aspar - Addition cylindrical tower

Construction

The structure was built of alternating bands of brick and stone, which were not of similar heights to the bands in the walls of the reservoir itself, suggesting that is was an added structure. The stone bands contained occasional vertical bricks, a technique that suggests a Middle Byzantine date, probably after the late tenth century.

A cylindrical tower capped by a semi-dome in the north corner of the reservoir. The tower presumably served to reduce the pressure of water exiting the reservoir. The tower was built beside the north-west wall of the reservoir, and if the location is significant, it is possible that the water was used to supply the north-west of the city, that is, the area around the Blachernai Palace.
