St. Mary's Lighthouse is on the tiny St. Mary's Island, just north of Whitley Bay on the coast of North East England. The small rocky tidal island is linked to the mainland by a short concrete causeway which is submerged at periods of high tide. The lighthouse and adjacent keepers' cottages were built in 1898 by the John Miller company of Tynemouth, using 645 blocks of stone and 750,000 bricks. It was built on the site of a monastery where a small sanctuary light would have acted as a guide to passing ships. The lighthouse was decommissioned in 1984.
Taken yesterday evening just after the tide washed over the causeway.
