Bardsey Island Lighthouse

Highlight • Structure

Bardsey lighthouse is the island waypoint, not only for ships as it can be seen from all other parts of the island as well. The island itself is two miles long by a half mile wide and is surrounded by sharp outcrops of rock. Recognising that a light was required to keep vessels to the west of the Llŷn Peninsula it was built in 1821 in order to mark the island for vessels northbound and southbound in St George’s Channel. It is now solarised and fully automated.

It is a wonderful part of the island being out on a headland and great views of Mynydd Enlli and the rest of Bardsey Island can be had from here.
