One of the Copeland Islands, with an area of 31 acres, off the coast of north east Co Down. The name reputedly comes from the sea mews (gulls) which nest there.
The present lighthouse and fog signal on Mew Island was established on 1st November 1884 when its predecessor, on Lighthouse Island, was discontinued. It was converted to automatic operation with the lighthouse keepers permanently withdrawn on 29th March 1996. The station is in the care of an attendant. The aids to navigation are also monitored via a telemetry link from Irish Lights Dun Laoghaire.
