Boundary Wall to Vaynol Park, including railings along the Menai Strait shore.

The wall is of local snecked and rock-faced stone rubble with fine Dinorwic slate copings closely and jaggedly set to project both sides. It begins at the N end near the road junction of the A487 and A5, SE of the Britannia Bridge, and runs downhill (S) past the entrance to the Vaynol Farm drive and that of Capel-y-Graig Lodge as far as the roundabout junction of the A487 with the A4087. It then turns SW past the fine main drive entrance in front of the Grand Lodge, and continues in a highly distinctive crinkle-crankle fashion as far as the junction with the B4547 where the walls steps back behind Nant Cottage - the story is that the owner refused to sell so that the wall had to divert behind it. Beyond, the wall borders a narrow winding stretch of road as far as the entrance gate piers to the lane to Caerefail (Aberpwll), set at right angles and facing into Felinheli. It then turns inwards, crossing and following the course of the Nant-y-garth, past the tall gate piers at Bryntirion lodge. The wall meets the Menai Strait shore at the harbour at Port Dinorwic. From there a lower boundary wall follows N along the shore line including a stretch near Vaynol Dock and Boathouse, which has iron railings on a stone plinth. At 25253 36838 this wall spans the mouth of a short canal that once served an earlier lime kiln, it passes then under the W drive. A railed clair-vue breaks the wall opposite Bath Cottage.
