Cirencester Abbey Gatehouse is a stone Norman gatehouse of the Augustinian Abbey of St Mary, founded by King Henry I. Built in 1180, on the south bank of the River Churn, the single-storey gatehouse with its attic, was the abbey's main entrance. The gate has a large vehicular and a small pedestrian archway at the front, with a large single archway at the rear. To the south-east, are the remains of the wall of the Roman town. 6 miles south is Ashton Keynes Castle and 8 miles east is Quenington Knights' Gate.
