Remains include a Norman Motte, 11th century Curtain Wall and 15th century Gatehouse. Information panels situated around the gardens tell the history of the Castle site, which has been in continuous occupation since the Norman Conquest.
The Gatehouse is now in use as offices of Hertford Town Council. Open days with free Band Concerts take place in summer.
