The Isles of Scilly are low lying islands off the West tip of Cornwall. They have a sub tropical climate due to the Gulf Stream and can be idyllic on a sunny day. Celtic saints were drawn to these remote islands as they were to other 'edge of the world' places because they felt they were 'thin', a place where heaven and earth could touch. It's thought that at one point many of the islands had hermits living on them or small prayer communities. This is Purpitch Beach on St Martin's, a place remote, beautiful and peaceful with little interference from the noise of people.
