Wychurst is a full-scale replica of a defended manorial burgh built by Regia Anglorum on three acres of freehold land in Kent, near Canterbury and about sixty miles from Central London. It features a flooded ring ditch, two hundred and twenty metres of palisade enclosing one acre, and a Longhall measuring sixty feet by thirty feet by thirty feet, which Regia describes as the largest building of its kind in Britain. The site is used for educational visits and member immersion events.
Regia Anglorum owns seven vessels. These range from a fifty-foot vessel that is no longer sea-worthy, through three forty-seven-foot hulls suited to inland and coastal waters, to a thirty-five-foot replica in active use and two twenty-foot smallcraft including a replica of the Gokstad Faering.

Television credits include Time Team (six appearances), Blue Peter (four occasions), Michael Wood's Beowulf, Blood of the Vikings, 1066: The Battle for Middle Earth, A History of Britain, and a National Geographic series about the Staffordshire Hoard.
