At the garrison fort of Carvoran, this museum makes an excellent introduction to Hadrian's Wall. Full-size models and excavations bring this remote outpost of the empire to life; authentic Roman graffiti adorns the walls of an excavated barracks. There's a well-designed museum with Roman artifacts and a flashy 3D film that puts it all into historical context. Opposite the museum, at Walltown Crags on the Pennine Way (one of Britain's long-distance national hiking trails),
are 400 yards of the best-preserved section of the wall. The museum is 1 mile northeast of Greenhead.
