Milefortlet 5 (Cardurnock) was a Milefortlet of the Roman Cumbrian Coast defences. These milefortlets and intervening stone watchtowers extended from the western end of Hadrian's Wall, along the Cumbrian coast and were linked by a wooden palisade. They were contemporary with defensive structures on Hadrian's Wall. The remains of Milefortlet 5 was excavated in 1943-4 prior to its destruction in 1944.
Milefortlet 5 was situated in a field just south of the hamlet of Cardurnock in the civil parish of Bowness.[1] The site lies within a disused wartime airfield, now under pasture. There is nothing to see on the ground, but aerial photographs taken in 2006 show the cropmarks of the northern end of the milefortlet.[1]
The coastline to the south is interrupted by Moricambe Bay, and the next known fort is Milefortlet 9. Milefortlets 6, 7 and 8 were once thought to have been eroded by Moricambe, but there is in fact no evidence that the sites ever existed,[2] and the system is believed to begin again with Milefortlet 9.[3]
Excavations
The milefortlet was excavated in 1943-4 prior to the construction of an airfield.[1] Three phases of construction could be traced. Phase 1 dated to the Hadrianic period. Phase 2 dated to the Antonine era, when the size of the milefortlet was reduced.[1] Phase 3 seems to date from the 4th century.[1] In Phase 3 the ramparts were retained but they were refaced on the south, west and north sides, and it seems a stone building in the fortlet was built during this period.[1]
A Roman road has been traced to the southwest of Milefortlet 5, and it was excavated in 1992–3.[4]
