Milefortlet 25 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. Milefortlet 25 is the southernmost known of the fortlets of the Cumberland coast, but there is nothing to see on the ground, as Milefortlet 25 lies in an industrial area of Maryport.
