Excavation in 2000-2002 found a gully associated with a Roman temple, probably dating to the mid 2nd century. The temple continued in use probably until the early 3rd century. The gully was relatively broad and shallow, up to 2 m wide and 0.40 m deep, and extended along most of the north-east side of the temple structure. It seems most likely that it was dug as a drain to carry water run-off from the roof, and the fact that this was apparently channelled into a tank rather than into the
river may be of significance in terms of the use of the Sanctuary complex. (1)
