Excavation in 2000-2002 found a clay and timber lined tank which was associated with a Roman temple, probably dating to the mid 2nd century. The temple continued in use probably until the early 3rd century. The tank measured approximately 2.50 m by 2.25 m and 1.0 m deep . The clay lining had slumped around the sides, but traces of probable planks did survive around the base and in the bottom. An inlet on the north western side of the tank to was allow water from the neaby gully to flow into it. The fact that water from this gully channelled into the tank rather than the river may be of significance in terms of the use of the Sanctuary complex. Fills related to its disuse have been dated to the late 2nd or early 3rd century. (1)
