Dock at NW edge of Vaynol Park, (including the boathouse)

The dock at the northwest edge of Vaynol Park, which includes the boathouse, is approximately quadrant shaped. It features a curved rubble breakwater on the north side and a straight quay on the south side, which includes stone steps. Both moles have rounded ends, and the breakwater curves back to end beneath the east side of the boathouse. The boathouse has a deeply hipped slate roof that is laid diagonally and a verandah on the south side supported by cylindrical columns, reminiscent of Wern-y-Gogas. The full height openings on the west side have been extensively modernised. The dock itself has undergone alterations, including the insertion of concrete ridges at the base, which may conceal outfall pipes. At the mouth of the dock, there are remains of what was possibly a stop-gate.
