Description

This is a 19th-century pigsty, likely built around the same time as the improvements made to the water-powered corn mill in 1859. The pigsty is constructed from low rubble and features an old slate roof. It has two yards at the front, which are enclosed by iron gates. At the time of inspection in December 1993, the area was overgrown.
