 Two rows of buildings are visible within, probably barracks, one either side of the north–south road running through the gateways.Interior buildings are not normally so well-preserved or substantial in other milecastles and local people, "mining" the milecastle for building stone in the past, may have recognised the layout as similar to stable-blocks.The walls are broad gauge, including stub 'wing walls' which connect with the Narrow Wall curtain of Hadrian's Wall on either side.
