Capel Celyn, Bala, LL23 7NY

Capel Celyn was a rural community to the northwest of Bala in Gwynedd, Wales, in the Afon Tryweryn valley. The village and other parts of the valley were flooded in the Tryweryn flooding of 1965 to create a reservoir, Llyn Celyn, in order to supply Liverpool and Wirral with water for industry. At the time the village was one of the few remaining Welsh‑only speaking communities. The locality, now part of the reservoir area, reflects a history of rural life and significant environmental change. Its postal district is LL 23, indicating its placement within the broader region of Bala and surrounding Gwynedd. The site’s history is marked by the transformation of a once‑vibrant community into a water‑storage facility, a narrative that underscores the area’s unique cultural and geographic heritage.
