Hog Island Shoal Light
Lighthouse
From Wikipedia, the free encyclopedia
Hog Island Shoal Light, built in 1901, is a sparkplug lighthouse on a shoal off of Hog Island, Rhode Island.[2][3][4] It is located about 600 feet (180 m) southeast of the island, at the entrance to Mount Hope Bay. It stands on a circular concrete Foundation (engineering) set in about 10 feet (3.0 m) of water, and rising about 6 feet (1.8 m) above the water line. It was built to replace a light ship, and was the last light station formally established in the state.[5] The lighthouse was automated in 1964. In 1988 it was added to the National Register of Historic Places.[1] In 2006 the lighthouse was auctioned by the GSA (General Services Administration) as government surplus to a private buyer.
