DescriptionTrelowgoed Mill, set on the north bank of the River Ithon, has an undershot waterwheel, clearly visible in a post-1880 postcard reproduced on p.54 of Melin 21 (the Journal of the Welsh Mills Society, 2005). The wheel runs in a channel off the main river and appears to be about 15 feet (4.6m) in diameter.
