Medieval longhouse.


Prior to investigation in 1957, there were clear surface indications of a building in the interior of the fort, but excavation proved it to be rectangular and orientated NW-SE, with bowed walls and internal measurements of 7.5m by 4m.


There was a possible entrance 2m wide in the south-east corner, but no trace of stonework. Another possible entrance pierced the wall on the north-east, though this lay perilously close to the cliff edge. Apart from a few postholes for support for the roof and entrance, little else survived to indicate the construction of the walls, which seem to have been of earth and turf. There was a rudimentary raised bench along each long wall and at the west gable, formed by cutting down into the bedrock in the centre of the building. There were also signs of a central hearth, though this took the form of burnt material rather than a built structure.


The excavator believed that the house represented Medieval reoccupation of the site.
