As well as the main island of Mann itself, the Isle of Man includes some nearby small islands: the seasonally inhabited Calf of Man; Chicken Rock on which stands an unmanned lighthouse; and St Patrick's Isle and St Michael's Isle, both connected to the mainland by permanent roads/causeways.
The Isle of Man is located in the middle of the northern Irish Sea, approximately equidistant from the islands of Britain and Ireland. In the context of Britain, the island lies closest to Scotland followed by England and then Wales.
The Isle is 52 kilometres long and 22 kilometres wide at its widest point. It has an area of around 572 square kilometres.
Hills in the north and south are bisected by a central valley. The extreme north is exceptionally flat, consisting mainly of deposits built up by deposition from glacial advances from western Scotland during colder times. There are more recently deposited shingle beaches at the Point of Ayre. The island has only one mountain higher than 600 metres, Snaefell, with a height of 2,037 ft.isle of man castle
