Teän ( ; sometimes written ''Tean'' without the diaeresis) is an uninhabited island to the north of the Isles of Scilly archipelago between Tresco, to the west and St Martin's to the east.〔Weatherhill, Craig ''Cornish Placenames and Language''〕 Approximately in area the island consists of a series of granite tors with the highest point, Great Hill, rising to at its eastern end.〔Ordnance Survey: Landranger map sheet 203 Land's End ISBN 978-0-319-23148-7〕 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.〔(【引用サイトリンク】url=http://www.naturalareas.naturalengland.org.uk/Science/natural/profiles%5CnaProfile113.pdf )〕 There is evidence of occupation from the Bronze Age to the early 19th century and the island was still being grazed in 1945.〔Parslow, R. (2007) ''The Isles of Scilly''. New Naturalist Library. London: HarperCollins〕 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 an Higher Level Stewardship (HLS) agreement. ==History== The coastline of Teän consists of a number of bays and sandy beaches which link to offshore rocks and carns at low tide. The western part of the island has low-lying ground linking granite carns, and field boundaries from the Romano-British period can be seen at extreme low tides.〔 One of the carns, Old Man, has an early structure, a Bronze Age entrance grave, as does Great Hill in the east of the island. Roman type brooches have been found in a grave on Old Man. Sixteen early Christian graves have been found under the east wall of St Theona's chapel which was built later on top of the graves. There was probably an earlier wooden chapel.〔Reid, N. (2007) ''Isles of Scilly Guidebook''.〕 A Parliamentary survey of 1652 reported one man living in a ruined house on the island 〔Thomas, C. (1985) ''Exploration of a Drowned Landscape: archaeology and history of the Isles of Scilly''. London: Batsford〕 and, in 1684, there was a thatched cottage between East Porth and West Porth which belonged to a Mr Nance who is reputed to have introduced kelp burning to Scilly. Kelp burning provides sodium carbonate for glass making and the practice continued in the islands until 1835. Kelp burning only produces 2-3 percent sodium carbonate and during the 19th century more efficient commercial and industrial methods ended the practice locally. Rights to areas of kelp were allocated to families and in 1787 Thomas Woodcock, his son and James Ashford (all of St Martin's) were accused of ″ having trespassed on his (Nance's) preserves″. After the hearing the court decided that the cutting of ore-weed and the making of kelp on Teän was the prescriptive right of Nance, and the trespassers were fined 2s 6d each. His family continued to live on Teän for several more generations and by 1717 there were ten people living on the island, but in 1752 William Borlase only saw fields of corn and ruined buildings.〔 In the 19th century Woodley reported occasional occupation, a few acres of cultivation and sheep grazing〔Woodley, G. (1822) "A View of the Present State of the Scilly Islands". London. In: Parslow, Rosemary (2007) ''The Isles of Scilly''. (New Naturalist Library.) London: Collins ISBN 0-00-220150-X〕 and a 1919 guide book reported just a rabbit warren. Cattle were still being grazed in 1945.〔Grigson, Geoffrey (1948) "The Scilly Isles". London: Paul Elek.
