The secret UK village submerged underwater that's Britain's answer to Atlantis

In 1955, was in desperate need of a reliable water source after a population surge hit the UK in the 20th century. To accommodate the millions of gallons of water the city needed, authorities decided to build a new reservoir.

However, Liverpool City Council's decision came with a cost. It meant that a small village home in would have to pay the price.

Capel Celyn in the northwest of Bala was a community of 67 residents, which was flooded to create Llyn Ceylan, a 2.5-mile reservoir in Tyrweryn Valley.

The , of course, faced opposition, specifically from local authorities, and the villagers who formed the Capel Celyn Defence Committee after learning about the proposal just before Christmas in 1955.

But how was this allowed to happen?

In 1957 a private bill, sponsored by Liverpool City Council, was presented to Parliament. It includes the development of a water reservoir in the Tryweryn Valley as well as the flooding of Capel Celyn.

By gaining authority through an Act of Parliament, Liverpool City Council did not need to get planning approval from any relevant Welsh authorities and could avoid a planning inquiry in Wales, where objections to the proposal could have been voiced.

35 out of 36 Welsh MPs opposed the bill; however, in 1962, the bill was passed, setting the flood plans in stone.

Despite years of efforts to stop the plan, in 1965, Capel Celyn's buildings, including the post office, school, chapel, twelve houses and farms, were submerged in water and 48 out of the 67 residents lost their homes.

Today, the village which has been dubbed "Britain's Atlantis" can sometimes be spotted during periods of extreme hot weather.

Just two years ago, during the UK's hottest year on record, the valley was drained of its water, causing the village's ruins to be left out in the open. Pieces of pottery and kitchenware have also been discovered by those eager to find any signs of the destroyed village.

The sad tale of what was once a cherished community is often referenced in discussions regarding transferring powers to the Welsh government, and in 2015, the UK elections took place during the 50-year anniversary of the flooding.

The Conservative Party campaigned on the St David's Day Agreement, which aimed to grant additional powers to the Welsh government. After further discussions, the UK government lost its authority to intervene in any laws concerning water that the Welsh government enacted as part of the Wales Act 2017.
