Site Type (preferred type first) : POST MEDIEVAL CORN MILL
Status : Listed Building II
Description :
18th-19th century. Round tower only to which a large water mill was formerly attached. (RCAHMW, Undated)
Same as Melin Adda? certainly Melin Adda is later called Melin Issa or Melin Adda (1762). I think there was more than one mill at Melin Adda, although they were overlain by Woollen mills of the 19th century, all trace of which has now been removed, leaving only the windmill standing. A developed site. The water mill lay just below the windmill. No evidence, on the ground - it has all been destroyed relatively recently. Note Woollen mill to N - is this the site of the corn mill (PRN 36165)? The whole area became a complex of mills in 19th century. (Davidson, 2002)
Melin Adda Windmill (Penrefelin). Late C18 tower windmill, one of three mills in in a milling complex with adjacent buildings. Mill closed in 1912 and was restored and converted into a dwelling in the mid-1970s. The building is remarkable in being built above the fall of water - very unusually for a water-mill, implying a pre-existing mill lower down. It has a very shallow pitch on the roof. (Sharma, et al., 2005)
