This document sets out the results from an archaeological watching brief carried out by West Sussex Archaeology Ltd on behalf of the owner, at Pitlands Farm, Up Marden, West Sussex, in March 2017. The work was associated with the construction of an extension to the north-east of the Farmhouse. It had been thought that the demolition of an existing flint wall, and the subsequent digging of the foundation trench for the extension's north wall, might expose part of the remains of a Roman bathhouse, however the results indicate that such remains must lie further to the north.
