Brownrigg North tower 21b is a Roman coastal fortification located approximately 830 metres north west of Canonby Hall in Cumberland, forming part of the defensive network of the Cumbrian coast during the later Roman period. The tower belongs to a series of installations erected to protect the north western frontier of Roman Britain, likely dating to the third or fourth century AD when the empire intensified coastal surveillance and defence against maritime threats. As a tower structure within this fortified system, it would have served primarily for observation and signalling purposes, contributing to the broader strategy of territorial control along the Irish Sea coast. The site remains a significant archaeological witness to Roman military engineering and the extent of imperial authority in north western Britain during the late antique period.
