EDO6042 - Green Island, Poole Harbour, Corfe Castle (Time Team); evaluation 2003

Excavation of three small trenches and five test pits sited to examine geophysical anomalies and test the results of surveys by Bournemouth University. A number of ditches, a hearth base, a layer of burnt stone and charcoal, and a possible buried land surface were excavated. The ditches were interpreted as enclosures of late Iron Age date, as seen elsewhere. These features were sealed by a layer of colluvium resulting from agricultural activity in the west of the island. The colluvium was itself cut by later Late Iron Age and Roman features, comprising a ditch, hearth and two post holes. There was evidence for shale working and iron smithing in the Late Iron Age and into the early Roman period. Small quantities of medieval material were recovered, suggesting cultivation of some kind somewhere on the island.
