Melin Hywel is an eighteenth century corn mill, extensively restored in the early 1970s and again in 1985. The original building was extended in 1850, with a kiln to the north and a granary and cartshed on the south, the upper storey of the latter accessed from the side of the millpond at the south end. The pond feeds an overhead launder with a lifting trap to direct water to the overshot wheel, whose diameter has been enlarged by adding a second set of iron shrouds outside the original set. Inside, a two-stage gear train drives a horizontal layshaft which in turn drives three pairs of stones and a number of ancillary machines through belts and a vertical shaft.

A mill was recorded on this site in 1352. In the 1970s this was the only working mill in Anglesey, with a thriving business in animal feed, which ceased only a few years ago.
