I just googled the Priory at Lydbrook & found the following on Wikipedia

The Priory
The oldest surviving building in Lydbrook is today known as The Priory, which in fact had never been a Priory, but was originally known as Lidbrook Farm. Once the home of the Probert family. The architectural design requires a date in the mid-1500s for this building, owing to the close timbered framework when oak was more plentiful, as opposed to square timbered style of the later period. There is a secret room in this building and claims for tunnels extending from Courtfield and the Anchor Inn. A Priest hole has been argued for, but smuggling has been suggested as an alternative. The house is also reputed to be haunted.
