ValetudinariumAblution Block or Valetudinarium (wash-house or hospital?)

This building contained three pits for water storage. Due to these water tanks it is thought that this building is an Ablution Block, or possibly a Valetudinarium.

The building’s foundations were angled around the Gyrus, which suggests that it must have been built after the construction of the Gyrus.

In later centuries, a medieval corn oven had been built on top of the west end of this building.
