What is "derventio"

Derventio may refer to one of the following Roman sites in England:

• The Roman fort and settlement at Papcastle, Cumbria.
• Derventio Brigantum, the Roman fort and settlement at Malton, Yorkshire
• Derventio Coritanorum, the Roman fort and settlement at Little Chester, Derbyshire

Derventio was a Roman settlement at Papcastle on the river Derwent near Cockermouth.

It was the site of a Roman fort, which was originally built in timber and rebuilt in stone. There was also a civilian settlement ( vicus). There have been a number of excavations since the beginning of the twentieth century. The remains of the forts and part of the vicus have been designated an ancient monument. In the 12th century the Normans removed Roman stonework from the site and used it to build Cockermouth Castle.
