Derventio at Papcastle was a Roman auxiliary fort guarding the crossing of the River Derwent in west Cumbria, established under the Flavians (c.

It anchored the road running west from Carlisle to the Cumbrian coast and the Roman port at Maryport (Alauna), and developed a substantial extramural settlement that became one of the larger civilian agglomerations in the region.

Recent community-led projects (the "Discovering Derventio" survey) have mapped a considerably more extensive settlement footprint than previously recognised, including industrial activity and riverside struct
