The old village of Llanwddyn was flooded in 1888 when Lake Vyrnwy dam was built to provide water to Liverpool. The village had 40 houses, three public houses, a corn mill (nprn 308086) and a church (St John's). The new village of Llanwddyn was built downstream of the dam at NGR SJ 0207519055, and a new church (nprn 309969, dedicated as St Wyddyn) was built using funds donated by the corporation of Liverpool; a small turret was built to house the bell from St John's church.
