When the valley was flooded in 1965, the village and its buildings, including the post office, the school, and a chapel with cemetery, were all lost. Twelve houses and farms were submerged, and 48 people of the 67 who lived in the valley lost their homes. In all, some 800 acres (3.2 km2; 320 ha) of land were submerged. A new reservoir, Llyn Celyn, was formed. Many of the stones from the original chapel were re-used in the construction of the new Memorial Chapel.
