Denbigh Castle’s triple-towered great gatehouse is a striking sight. It is probably one of the seven wonders of Wales! The castle, now in the guardianship of Cadw, crowns a steep hill above the medieval town. 

Work on Edward I’s Denbigh Castle began in 1282 and was overseen by Henry de Lacy, one of the King’s loyal commanders. Building works were led by the King’s master mason, James of St George. A Welsh rebellion, led by Madog ap Llywelyn, captured the partly-built castle in 1294 but Edward’s dominance, and the castle-building programme, were soon restored. You can see for yourself the two phases of building work. The post-rebellion work is marked by different colour stone, thicker curtain walls and angular towers.
