Aberlleiniog Fishweir II, Llangoed

Primary Reference Number (PRN) : 14615
Trust : Gwynedd
Community : Llangoed
Unitary authority : Ynys Mon
NGR : SH62517930
Site Type (preferred type first) : Medieval FISH WEIR
Status : Scheduled Ancient Monument

Description :
An unusual rectangular weir that does not appear to run from the shore, utilising instead a raised natural stony bank at least 150m from the shore as its inner end. This could be an original design feature or a result of coastal erosion. Weir survives as a 115m x 12m inner arm from the bank to low tide mark and an outer 130m long outer arm of comparable width (at 90 degrees to the above). This arm does become narrower (6m) at the end. A further spur runs out from the centre of the outer arm into the channel. The function and phasing of this feature are unclear but it could be seen as a later addition or an earlier rectangular weir. The apex of the main weir is somewhat elongated presumably marking the remains of a sluice. A few roughly parallel stones could represent the sluice channel. Good anaerobic silts could retain preserved wood. (Hopewell, 2000).
