Description :
Llynon Mill. The remains of an 18th century circular tapering tower of a former windmill. Constructed of rubble masonry with grey rendering. It has four floors, the top one serving only as a protective covering. The roof is now missing and the sails have gone but the wooden sail arms remain with the cross battens partly missing. (RCAHMW, 1937)

1. The last tower mill in Anglesey to retain sails and machinery. Disused and derelict. Windmill had wooden rotating caps. 3 floors - machinery in middle floor. Four sails in good condition in 1929 (see Turner's notes). Recently collapsed but may be restored? Restored and walling (1987).

2. The only traditional working windmill in Wales. Built September 1775 - March 1776 at a cost of 529 11s 0d. Stone tower, rendered, four storeys with boat-shaped cap. Three pairs of millstones: one pair French burrs for wheat flour, one pair Anglesey stones for general milling, one pair open for view. Ceased milling by wind-power in 1924; restored to working order and opened to the public in 1984. (RCAHMW, Undated)
