Melin Hywel was 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 cart shed on the south, the upper storey of the latter accessed from the side of the millpond. The pond fed an overhead launder with a lifting trap to direct water to the overshot wheel. The diameter of the wheel has been enlarged by adding a second set of iron shrouds outside the original set.

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 in 1992. (I did consider buying this mill, but it was not to be)
