Lighthouse

The Skerries Lighthouse (53.4211°N 4.6085°W) was established on the highest point of the largest island after 1716. A patent for the lighthouse was subsequently obtained in 1824. The builder was William Trench, who lost his son off the rocks and died in debt in 1725. He is said to have originally been allowed a pension from the Post Office
