Description
Parys Mountain Windmill is a late 19th century tapering circular windmill tower that stands three storeys tall. It features opposing doorways on the ground floor and single windows on the upper storeys. The structure is constructed of rubble masonry, with cambered brick heads above most openings. While the tower is almost complete, it does show some damage at the top and has holes between the ground and first floor levels. There are no remaining machinery components.
