Bremenium (High Rochester) is an ancient Roman fort (castrum) located at Rochester, Northumberland, England. The fort is part of the defensive system built along the extension of Dere Street, a Roman road running from York to Corbridge and onwards to Melrose. Significantly the fort is a long way north of Hadrian's Wall. It was one of the last forts north of Hadrian's Wall to remain occupied until the 270s.
