Milecastle 25 (Codlawhill) was a milecastle of the Roman Hadrian's Wall. Its remains exist as a low platform, and are located to the south of the B6318 Military Road (about 1 metre (3.3 ft) high), nearly 5 kilometres (3.1 mi) to the west of its junction with the A68.

Construction

Milecastle 25 is believed to be a long-axis milecastle with unknown gateways type. Such milecastles were thought to have been constructed by the legio VI Victrix who were based in Eboracum (York). The milecastle measured 15.24 metres (50.0 ft) across, and had broad east and west walls (the curtain wall at this point was also broad gauge). The north gateway and wall are beneath the road. There are possible traces of a milecastle ditch to the south, but no traces of a spur from the Military Way despite evidence of causways over both the ditch and vallum ditch at this point.
