The settlement on Nor'nour, a small island in the eastern group of the Isles of Scilly, presents a most unusual complex of at least three structural phases, accompanied by a rich and varied assortment of artifacts in bronze, enamel and pottery. Roman jewellery was made on the site, which was excavated from 1962 to 1966. The presence of a Bronze Age population was clearly indicated. A room built in the form of a Scillonian Passage Grave, with sherds similar to those of the primary urns at Knackyboy Carn, suggest a date of c. 1200 B.C. for this group. In the early Iron Age, c. 600 B.C., immigrants from western Europe, particularly perhaps from Brittany, reached the island. Room I was altered to the form of a wheelhouse, which still clearly shows the features of its type. At the same time a D-shaped room was added to the eastern side of the wheelhouse and seems to have been used as a kitchen. An extensive kitchen-midden lay east of this additional room and to the north-east a workshop was made containing three well-made pits and an enclosed hearth or furnace area. The latest phase showed a complete change; the wheelhouse became the finishing-room in the manufacture of Roman jewellery and, probably, a store for the import and sale of objects from western Europe. Roman coins found here date from A.D. 74 to A.D. 383. There is also some evidence for the early and gradual subsidence of the Scillonian archipelago.
