The Isles of Scilly are an archipelago off the South West tip of Cornwall. Around two hundred rocky islets make up the Scillies. The five islands of St Mary's with its main settlement of Hugh Town, Tresco with New Grimsby, St Martin's with White island, St Agnes with Gugh and Bryher with Gweal are inhabited by two thousand two hundred people and are part of the Duchy of Cornwall. Islanders used to speak the Cornish language but this died out in the late Middle Ages.
