An archaeological watching brief was undertaken by Oakford Archaeology in March 2022 at Southcombe Barn, Widecombe-in-the-Moor, Devon . A watching brief was maintained during works associated with the installation of a new concrete floor within the northern part of the barn. The work involved internal ground reduction to a depth of 0.5m. The works exposed the remains of a possible early 19th century NE-SW aligned stone drain. In addition, a small collection of post-medieval material was recovered from the works. Nothing of significance was found
