The ringfort by the sea : Archaeological geophysical prospection and excavations at Sandby borg (Öland)

• Archaeological investigations and clear aerial photos have identified the presence of house foundations within several ringforts on the island of Öland, east of the Swedish mainland. One of them, Sandby borg, was selected for further investigations by means of a ground-penetrating radar (GRP) and magnetometry survey. A subsequent excavation was carried out to validate the geophysical results. The results of the geophysical survey clearly show the presence of 36 or 37 stone foundations for houses situated radially around the wall of the fort as well as of 16 or 17 similar house foundations in a central building group. The geophysical results also provided information on other buried features within the fort and also confirm the location of a third gate situated in the north-western part of the fort. The available evidence indicates that the ringfort was used for military purposes, or as a place of refuge in times of unrest, for a limited period of time during the late 5th century.
