Main image

St Mary’s Island is a small tidal island off the North East coast of England in Tyne and Wear, close to the town of Whitley Bay. The island is linked to the mainland by a stone causeway that is exposed at low tide, making it a short walk from the shore when tides permit.

The island’s main structure is a lighthouse and associated buildings, and the site is used for short visits, coastal walking and wildlife observation rather than extended stays. Facilities on the mainland adjacent to the island support visitors with parking and paths to the causeway.

Historically the lighthouse on the island was established in the late 19th century and has been a navigational aid for vessels along this stretch of coast; the island and lighthouse are now also maintained as a local amenity and visitor attraction.

Geographically the island sits just off the coast at Whitley Bay on the North Sea coast of Tyne and Wear, north-east of Newcastle upon Tyne and easily reached by road from nearby coastal towns.
