Heritage Open Day: Visitors can see the remains of the commanding officer's house of the fourth century fort, including the impressive bath building, which contains one of the best preserved examples of a hypocaust (underfloor heating system) in the whole of Britain. The late Roman bath-house at the centre of the fort has recently been endowed with updated interpretation panels featuring reconstruction images to give the visitor a far better understanding of what the building looked like originally. Visitors can also see part of the exceptionally well-preserved regimental bath-building outside the fort, with its walls still standing to a height of 7 feet above Roman floor level. The site also features a new reception building offering greater space for publications, souvenirs and a range of ice-creams.
Entry is free during the Heritage Open Days period. Self-guided tour with an introduction by site staff.
