About 8 miles east of Greenhead, this archaeological site holds the remains of eight successive Roman forts and civilian settlements, providing an intriguing look into the daily life of a military compound. Most of the visible remains date from the 2nd and 3rd centuries, and new excavations are constantly under way. A reconstructed Roman temple, house, and shop provide context, and the museum displays rare artifacts, such as a handful of extraordinary wooden tablets with messages about everything from household chores to military movements. A full-size reproduction of a section of the wall gives a sense of its massiveness. The site is sometimes closed in bad weather.
