The remains of a lost village are hidden underneath a reservoir used to supply Liverpool with drinking water.
Llanwddyn was once a small village at the head of Vyrnwy Valley in Powys, Wales.
But by 1880 the valley had been identified as a suitable site for the reservoir.
Despite opposition from residents of the village, who were not consulted about the proposals, an act was passed and work began the following year to build a dam across the valley.
The work took around seven years to complete and in 1888 the old village was demolished and the area flooded.
A church, two chapels, three inns, 10 farmhouses and 37 other houses were lost under the rising waters.
A new village was built by the Liverpool Corporation around two miles further down the valley, to house the original residents.

Today the reservoir, called Lake Vyrnwy, is a popular destination for tourists.
During a drought season the remains and foundations of the lost village can still be seen.
Photos from our archives show the remains emerging from the water for the first time since it was flooded, in the drought of the summer of 1976.
Llanwddyn is not the only welsh village that was submerged to create a reservoir to provide a water supply for Liverpool and Merseyside.

Perhaps the most well known is the small welsh village of Capel Celyn in Bala, which was flooded in 1965.
Like the lost village of Llanwddyn, any evidence of Capel Celyn's existence can only been seen during heatwave conditions when the reservoir dries out.
