Located on Bait Island, St. Mary’s Lighthouse and its cottage were built in the late 19th century. The cottage went on sale several years ago for around $553,000.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 an 11th-century monastic chapel, whose monks maintained a lantern on the tower to warn passing ships of the danger of the rocks.
