Teän

Teän ( TEE-ən, sometimes written Tean without the diaeresis; Cornish: Enys Tian) is an uninhabited island to the north of the Isles of Scilly archipelago between Tresco, 1.5 kilometres (0.9 mi) to the west, and St Martin's, 300 metres (330 yd) to the east. Approximately 16 hectares (40 acres) in area, the island consists of a series of granite tors with the highest point, Great Hill, rising to 40 metres (130 ft) at its eastern end. The low-lying land is overlain with glacial till and outwash gravels with glacial erratics abundant on the north coast beaches, which indicates the southern limit of outwash from an ice sheet for which it is designated a Geological Conservation Review site. There is evidence of occupation from the Bronze Age to the early 19th century and the island was still being grazed in 1945. An early Christian chapel exists on the island; it was possibly dedicated to a saint called Theon. The island lies within both the Isles of Scilly Heritage Coast and the Isles of Scilly Area of Outstanding Natural Beauty. It is managed by the Isles of Scilly Wildlife Trust, which has a Higher Level Stewardship (HLS) agreement.
