It has been under excavation since 1981, and almost all of the interior and the entrance of the fort has been examined, together with a significant section of the farmstead. The fort is one of the most extensively excavated ever in Britain. The excavations are run so as to provide practical training, and Castell Henllys is now the longest-running and largest such excavation in Britain. Three-quarters of the castle have been examined and it is likely that the work will be completed in another two seasons. Dolforwyn was the last castle built by Llywelyn ap Gruffydd in the 1270s.
