Architecture, archaeology and continuing use
The fort and annexe remain visible within multiple ditches beside the Wall. Quarry pits flank the Military Way, while a group of ten rows of lilia pits marks the approach. Excavation located headquarters, commander’s house, granary and bathhouse without reconstructing them above ground.
Its story
Rough Castle formed one of the closely spaced forts along the mid-second-century frontier. Excavations in 1902–03, the 1930s and the 1950s revealed its internal organisation. Later guardianship made the earthworks one of the most publicly legible Wall sites.
Why it is included
National importance rests on exceptional survival and the rare ability to read an entire frontier complex rather than an isolated ditch or building trace.
What to notice
- Fort ditches enclosing the central platform.
- Annexe and Military Way beside the main enclosure.
- Rows of lilia defensive pits near the Wall crossing.
Reading the surroundings
Follow HES paths and current notices, wear footwear suitable for uneven wet ground and keep dogs under control. Never enter pits, dig, remove material or cross fences into neighbouring land.

What we know — and what remains uncertain
The visible banks are archaeological earthworks, not complete Roman wall heights. HES opening information does not guarantee dry or step-free access across the site.
