Belas Knap

I was there 2 years ago, dragging the wife, my (then) 2-year-old and the in-laws up the hill, to get a real taste of I feel is the Right Ancient stuff. Although they were pantingand moaning, they really appreciated the site.
Does anyone know that when you walk back down to Winchcoombe, there are the remains of a hidden Roman villa just below the treeline, with a beautiful mosaic?
