Near the end of the Exmoor information film shown at the Pavilion we noticed an aerial view of a very well-defined roman fort we had not seen before. We did not even know where it was until we asked the Pavilion staff. We visited the site a couple of days ago and it is very impressive. It is easily reached from a car park on the A39 near Countisbury, then a 15-minute well-marked walk. It would also be an easy detour from the Coastal Path if you were passing through.
