Overview

History & significance

Aberlleiniog Fish Weir II is a post-medieval fish weir located at Aberlleiniog on the island of Anglesey, Wales. The structure represents the exploitation of tidal waters for fish capture, a practice of considerable antiquity in Welsh coastal communities but one which continued and was refined during the post-medieval period. The weir's physical form reflects the engineering principles employed in constructing barriers to trap fish on retreating tides, utilising the natural topography of the foreshore. As a scheduled ancient monument under the Cadw register, it retains archaeological significance as evidence of the maritime economy and subsistence patterns of early modern Anglesey.
