Castles that have stood for hundreds of years are at risk of being damaged by climate change, conservation charity English Heritage warns.
The charity, which manages over 400 historic sites across England, highlighted six castles threatened by coastal erosion and rising sea levels.
They include Tintagel in Cornwall and Hurst Castle in Hampshire
It is appealing for money to repair walls and improve defences against storms and more powerful waves.
“It seems to be that the whole natural dynamics of the coastline in some places have been accelerated by climate change,” Rob Woodside, English Heritage’s estates director said.
“What we’re trying to do now is essentially buy time, so with places that we value, and people want to look after, we put measures in place to protect them.”
