Lewes Castle was built soon after the Norman Conquest by William de Warenne, one of William the Conqueror’s closest allies from the Battle of Hastings. Begun around 1069, it was the second Norman stronghold in Sussex after Hastings Castle — chosen for its commanding ridge above the River Ouse and the route to London. Its twin mottes and flint walls still dominate the landscape nearly a thousand years later, a reminder of how swiftly England changed after 1066. #LewesCastle #SussexHistory #Norman
