On the site of the Carvoran Roman Fort a mile northeast of Greenhead, near Walltown Crags, this revamped museum has three galleries covering the Roman army and the expanding and contracting Empire; the wall (with a 3D film illustrating what the wall was like nearly 2000 years ago and today); and colourful background detail to Hadrian's Wall life (such as how the soldiers spent their R&R time in this lonely outpost of the Empire).
