anti tank gun and machine guns. Museum More recently Fort Grey has been adapted for other more peaceful uses and now operates as a local shipwreck museum, housing a number of items of marine salvage from famous wrecks, including the and Elwood Mead. The items also include a cannon from that points towards the nearby Hanois rocks where Boreas sank in 1807 with the loss of her captain, at least half her crew, and possibly the captain's wife. An additional exhibit of the timbers from a 3rd-century Roman ship, nicknamed "Asterix", found in St Peter Port harbour in 1982 will shortly be on display close by, having taken decades to preserve the 1,700 year old timbers. Protection The whole of Fort Grey and the slipway at Rocquaine was listed as a Protected Monument on 26 March 1938, reference PM238. Notes References References Clements, William H. (1998).
