This image shows the old "fort" (probably a villa), a canal, a railway, the nearby church in Coates village (one of two in Gloucestershire that have an anthropophagus) and some footpaths.
If you look on LIDAR data you see the spoil heaps from digging the canal tunnel (between Coates and Sapperton.

Sadly, this interesting site has been plundered by irresponsible detectorists, and much of it has been ploughed over.

It's weird to me that we have this site and we're happy to just lose all that stuff.
I wonder if and hidden roads with stones are left.
