Community : Llangoed
Unitary authority : Ynys Mon
NGR : SH62107860
Site Type (preferred type first) : Unknown FISH WEIR
Status : Scheduled Monument

Description :
Gored Tre-Castell, good stone foundations survive on the N side with the remains of stakes still set into the centre. A row of large boulders to the N suggest different phases. <2>

Well preserved subrectangular weir defined by spread banks of stone. The wall from the shore varies from a 20m wide bank to a 1.1 to 1.6m wide double line of facing stones very similar in appearance to that found on top of Gorad Bach (PRN 892). The outer wall clearly exhibits two phases both with spurs. The inner of the two is 7m wide, the outer10m wide. Two additional possible spurs run out into the channel of the Straits from the outer phase. As both walls are nothing more than stone banks it is impossible to say which is earlier. Several other vague alignments of stone can be seen from the Aps. One seemingly running from the inner arm of the gorad. This could be an earlier phase. The other stones are probably the remains of oyster beds. (Hopewell, 2000).
