Reached between the tides via a short causeway, St. Mary's has all the fascination of a miniature, part-time island. The Lighthouse, completed in 1898 on a hazardous coast for shipping, remained operational until 1984 when it was superseded by modern navigational techniques. Since then the Lighthouse and former keepers' cottages have been operated as a visitor centre by North Tyneside Council. The surrounding Nature Reserve contains an area of rockpools, clifftop grassland, a beach and newly created wetland habitats.
