Description
The piggery at Penychain is a 19th-century structure made of stone with slate roofs. It features four pig sties, each with open runs on either side. The sties have dual feeding troughs located on the west side, which are accessed from the rear. Each sty includes a low single opening that leads to the run. In the runs, there are slate troughs positioned under feed hoppers for the pigs. Access to the sties is provided by a narrow passage that has contemporary slatted iron gates, which lead from the farmyard at the southern end of the small feed building. The northern end of the passage is bordered by a high crenellated perimeter wall that connects the north wall of the cowhouse range with the garden wall of the house.
