Site 2: Gozo Citadel - Lower Corralline Limestone Display

The part of the Citadel in which the access point was located was built in the 15/16th century. However, it is beleived that the cistern itself dates back to 3rd century BC.

This cistern was approximately 30 feet below the access point. It incorporated a small rectangular chamber with a passageway to a much larger chamber. A few objects littered the bottom. A short video of what the robot saw can be found here.

Shown below is the sonar data image, a top view of the mapped image (0.20m grid cell resolution) and a 3D view of the mapped image (0.05m grid cell resolution).
