Community : Menai Bridge
Unitary authority : Ynys Mon
NGR : SH55117184
Site Type (preferred type first) : UNKNOWN DAM

Description :
A stone dam, 3.5m wide at the base and 1.5m wide at the top at 1m in height. A further low wall is built on top of this one. Possibly the dam associated with the mill in this location.

Two dams run between Church Island and the shore. Records of a double tidal mill and associated fisheries survive from the 16th century. The tidal mill could well have acted as both a fish-trap and a mill. The westernmost dam is V-shaped and survives as a 3m wide stone spread, standing to a height of 0.5m. The remains of a sluice may survive at the apex. The position and plan of this dam is consistent with that of a fish weir. The other dam is more substantial and appears to be the remains of a tidal mill. (Hopewell, 2000).
