Retaining wall with small jetty in Menai Strait

The retaining wall with a small jetty in the Menai Strait is a Grade II listed structure. It features a sea wall and terrace that includes three semicircular bastions, with the central bastion supporting a flagpole. The walls are made of roughly coursed and squared masonry topped with flat slab coping and a plain stone band on the seaward side. Between the bastions, there are two rectangular projections that have Gothick arches below, which open onto the Menai Strait.

To the south, there is a covered dock or plunge bath with a brick arch ceiling, accessible via stone steps and a brick tunnel-vaulted passage. To the north, a narrow jetty projects into the Menai Strait, although part of it has been washed away. This jetty is reached through a subterranean room that has a Gothick arch flanked by two Gothick windows, one of which is blind. The room features a two-bay cross vault made of brick and has a stone bench along the rear wall, along with a fireplace that has a massive squared stone lintel.

At the southern end of the sea wall, there is a curving harbour wall and slipway, which includes a later parapet and a battlemented bastion set behind it. At the northern end of the harbour, a concrete swimming pool from the 1950s likely incorporates some of the original harbour wall, alongside a small stone building.
