Llyn Celyn, Water reservoir in Gwynedd, Wales
Llyn Celyn is a reservoir in Gwynedd, Wales, stretching at the foot of the Arenig Mountains and covering an area of around 320 hectares. The water reaches depths of roughly 140 feet and stores over 71 million cubic meters, surrounded by gentle hills and grassland.
Construction of the reservoir began in 1960 and was completed five years later, flooding the village of Capel Celyn along with farms, a school, and a cemetery. The relocation of residents sparked nationwide protests and shaped the Welsh political movement for decades.
The name Celyn means holly in Welsh, and the water carries the memory of the submerged village through memorial stones and plaques along the shore. Visitors today see a quiet water surface surrounded by wooded slopes, serving as a place for reflection.
Access to the shore is possible at several points, and walking paths run along the waterline with views of the surrounding mountains. The area is suitable for quiet walks, though the terrain can be uneven in places.
The water is deliberately released into the Tryweryn River to supply the Canolfan Tryweryn National White-water Centre with consistent conditions for canoeing and rafting activities throughout the year. This controlled release allows training and competitions regardless of natural rainfall.
