This is the report of the excavation of an enigmatic site in South Gloucestershire, which contained a decorated cellar with a cruciform setting of channels beneath its floor, almost certainly of 'ritual' significance, and a very large bath-house which included a swimming pool some fourteen metres long. Both the cellar and the bath-house had painted wall plaster and the bath-house contained a small area of tessellated floor. No other rooms were decorated in any way. The site dates from the late 1st Century AD and there was no evidence of any earlier activity apart from a number of randomly distributed flints, mainly Mesolithic.
