A woman was shocked to find her car disappearing down a large sinkhole at Craig-Y-Nos Castle, in the Brecon Beacons National Park.
The hole, which was about ten foot deep, swallowed castle assistant Karen Davies’ Fiat Panda bonnet first.
Son Luke, said Karen parked in her usual spot but was later told by colleagues about the sinkhole.
He said: “She was in shock and at first she thought it was a joke.
“The car was upside down.
“A customer was in the car park when it started sinking – they saw it happen and how it gradually went down.
“They spoke to a member of staff but by the time my mum found out the car had sunk completely.”
It’s not yet known what cause the sinkhole but workers believe it may have stemmed from a nearby stream eroding the ground under the car park.
