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.
