Capel Celyn was a small village located in the Snowdonia region of Wales. It was known for its picturesque landscape and close-knit community. In the 1960s, the village was controversially flooded to create a reservoir, known as the Tryweryn Reservoir, to supply water to the city of Liverpool. The flooding of Capel Celyn led to significant protests and discussions about the rights of local communities. The event is often cited in debates about water rights and the impact of large infrastructure projects on rural areas. Today, the site serves as a reminder of the balance between development and community preservation.
