This cistern was located in the hallway of the Wignacourt Museum and was acessed by putting the ROV through the window opening to the College Garden. The cistern itself was actually connected to the College Garden cistern.
Shown below is the sonar image illustrating the shape of the cistern. This site was another access point to the Wignacourt Museum College Garden cistern. It was very complicated with stairs (seen on right) and several pillars.
