Norman Conquest Encyclopedia
The fortification of Dover, already a naturally strong military position, was undertaken by William the Conqueror soon after his victory over Harold Godwinsson at Senlac Hill near Hastings. William had waited for the formal submission of the English after their king had been slain, but none came. After five days he left Hastings and moved east, taking care to send a detachment to Old Romney to avenge himself upon its unfortunate citizens, before accepting the surrender of Dover. Here he had a castle built within the existing enclosure. The castle was continuously developed over the next 900 years (English Heritage; tel.01304 201628).
