Denbigh Castle

Denbigh Castle and town walls were a set of fortifications built to control the lordship of Denbigh after the conquest of Wales by Norman King Edward I in 1282. The King granted the lands to Henry de Lacy, the Earl of Lincoln, who began to build a new walled town, colonised by immigrants from England, protected by a substantial castle and surrounded by deer parks for hunting. The work had not been completed by 1294, when the Welsh temporarily seized the castle during the Madog ap Llywelyn revolt. The defences continued to be improved, although the castle was not completely finished by the time of Henry's death in 1311.

The castle passed between various owners in the first half of the 14th century, before coming under the control of the Mortimer family. Meanwhile, the walled town had proved impractical to live in, and a newer, much larger, settlement developed outside the defences.
