Description

Melin Bodowyr is a water-powered corn mill. The main mill is a rectangular two-storey building featuring an external waterwheel in a pit at the left (east) end. It has rubble walls and a pitched slate roof. There is a central door at the front (north) that has been widened from its original size, along with a narrow door at the rear (south) wall. Small windows are present on the first floor. The original extent of the building is indicated by large stones at the quoins. To the left (east) of the door, there is a single-storey projection, likely used for storage. To the right of the door, there is a late 19th-century single bay addition made of rubble stone, which includes a small churn room at the right (west) gable end. The waterwheel features cast-iron rims, hubs, and sockets, along with wooden buckets and spokes.

To the southeast, at an angle to the main mill, is an earlier mill building that appears on the 1783 estate map. This building also has rubble walls and a slate roof, with a single door in the northeast wall. The waterwheel pit in this building has been infilled.

The mill retains all of its machinery, including a great spur wheel, pit wheel, wallower, and stone nuts, which drive two millstones located on the first floor. It previously had an overhead drive-shaft that powered a sack-hoist, cleaning box, and churn in the churn room at the west gable end.
