Point of Ayr is the northernmost point of mainland Wales and is north of Talacre, at the mouth of the Dee estuary.
It is in the southwest of the Liverpool Bay area of the Irish Sea. It is the site of a RSPB (Royal Society for the Protection of Birds) nature reserve, and is part of Gronant and Talacre Dunes Site of Special Scientific Interest.
The Point of Ayr Lighthouse was built in 1776 and was operational until 1844. The lighthouse once displayed two lights; the main beam, at 63 feet, shone towards Llandudno, while a secondary beam shone up the River Dee, towards the hamlet of Dawpool on the English side of the estuary. Whilst in service, the lighthouse was painted with red and white stripes, and had a red lantern housing. It was replaced in 1844 with a metal pile lighthouse, bearing a white light, put up by order of the Corporation of Trinity House.This new structure was replaced in 1883 with a lightship.
