Excavations
The site was excavated in 1899, when the stone fort was revealed. A buttressed granary was found within the north-west angle of the fort.
Excavations in 1947 revealed that the stone fort had been built within a slightly larger fort whose clay ramparts had been levelled. It is presumed that the earthwork fort had been added to the initial Turf Wall version of Hadrian's Wall in Cumbria, and that the stone fort replaced it when the Turf Wall was re-built in stone. This would date the stone fort to about 160 AD.
No sign of a
vicus has yet been detected near to the fort.
