Birdoswald is a particularly fascinating fort because it illustrates the continuity of occupation which existed at some of the 'Roman' sites along the wall. There are good stretches of the wall itself remaining either side of the fort and a milecastle not far away. The fort is a short walk (about 100 yards) uphill from the car park, but there is also disabled parking available on site. The gates and granaries have been excavated for visitors to view, including the re-erection of dark age posts to show how the buildings were later re-used. There is also a good little museum in part of the old farm and displays explaining the history of the site. The farmhouse, built by a Victorian antiquary to simulate a medieval pele tower, is now an archaeological studies centre and there is accommodation available for pre-booked groups.

The Site is run by Cumbria County Council & there is an entry fee. Free admission to members of English Heritage however.
