Carndochan Castle, Medieval castle ruins in Llanuwchllyn, Wales.
Carndochan Castle is a fortified site near Llanuwchllyn built on rocky ground with a distinctive D-shaped tower and rounded structures forming part of the outer defenses. The remains show how central buildings once stood within protective walls that controlled access to the hilltop.
The site was built in the early 13th century, likely under Llywelyn ap Iorwerth, a Welsh prince expanding his realm during a period of territorial conflict. The fortress played a role in power struggles that shaped the region's history.
The castle displays building methods that were typical for Welsh fortifications, showing how rulers protected their territories at the time. The way towers and walls are arranged reveals much about the defensive strategies of that period.
The site lies west of Llanuwchllyn village and requires a walk across open ground to reach the remains on the hilltop. Sturdy footwear is advisable as the terrain is uneven and exposed to the elements.
Archaeological digs at this location have uncovered Iron Age artifacts, showing that people lived here long before the castle was built. These finds prove the hilltop served as a defensive position centuries before the medieval fortress was constructed.
