The Prior's Mesne estate (including outlying lands at Newlands and St. Briavels) was based at Prior's Lodge (also known as Prior's Mesne Lodge or Bream Lodge.) It was cleared of trees by Llanthony Priory in 1306 and largely converted to agricultural land, and they allowed their tenants rights of common there. Prior's Pool was a fishpond dating from this time. The market cross was built in the 14th C. Llanthony Priory had a fulling mill on Ferneyley Brook in 1535 (later called Tucker's Mill or Wood Mill, later to be used as a grist mill until around 1900).
