Traces of a building on the south side of the lane from Tresisillt to St Nicholas mark the site of a gorse mill, whose wheel also drove a shaft to a threshing machine in the farmstead some 80 metres to the west. Water was carried in a leat from the tailrace of Felin Velindre some 600 metres to the north.
