Abercastle Mill/Felin Abercastell

Abercastle Mill, also known as Felin Abercastell, is an early 19th-century house and former mill. The building features a roughcast exterior and a grouted slate roof with end stacks. It is a two-storey, low, double-fronted structure with small square upper casements positioned above small plate-glass sash windows and a central door. To the left, there is a single-storey lower section that includes a door and a small window. The mill, located at the left end of the building and oriented at right angles, is constructed from gabled rubble stone and has an imitation slate roof. It features double doors at the north end under a timber lintel and a loft door in the side wall. The water wheel was situated in the south end wall.
