Halangy Down is a prehistoric settlement located on the island of St Mary's, in the Isles of Scilly. The ancient site covers the lower slope of Halangy Down hill, overlooking the coastal inlet between the island of St. Mary's and Tresco Island. On the site are the remains of an Iron Age village, two entrance graves, prehistoric field systems, standing stones, post-medieval breastworks, and a Victorian kelp pit.
Archaeological excavations have revealed that the first stone structures were built during the Iron Age (800 BC - 100 AD). Evidence shows that the buildings were continually altered and replaced over the 500 year period of occupation, from the later Iron Age to the Roman period of occupation in Britain (43 AD - 410 AD). The village was made up of a complex of attached stone houses. One house, a large multi-room residence with an interconnecting courtyard, had been built in the Romano-British period. The excavation findings included Iron Age, Romano-British and Anglo-Saxon pottery; flint and quartz tools; a slate spindle-whorl; several millstones; bronze brooches and iron slag.
Near Bant's Carn is a Bronze Age entrance grave located on a steep slope adjacent to Halangy Dwon. The tomb is one of the best examples of a Scillonian entrance grave.
References:The Broch of Clickimin is a large and well preserved, though somewhat restored broch near Lerwick. Originally built on an island in Clickimin Loch (now increased in size by silting and drainage), it was approached by a stone causeway. The water-level in the loch was reduced in 1874, leaving the broch high and dry. The broch is situated within a walled enclosure and, unusually for brochs, features a large 'blockhouse' between the opening in the enclosure and the broch itself. Another unusual feature is a stone slab featuring sculptured footprints, located in the causeway which approached the site. Situated across the loch is the Clickimin Leisure Centre.
