Climate change risk to coastal castles

Hearst castle wall collapses

A section of Hearst Castle in Hampshire collapsed in February 2021

The English Heritage charity warns that castles that have stood for hundreds of years are at risk of being damaged by climate change.

The charity, which manages more than 400 historic sites across England, has highlighted six castles threatened by coastal erosion and rising sea levels.

They include Tintagel in Cornwall and Hearst Castle in Hampshire

She appeals for money to repair walls and improve defenses against more powerful storms and waves.

“It appears that the natural dynamics of the coast in some places have been accelerated by climate change,” Rob Woodside, property director at English Heritage, told BBC News.

“What we’re trying to do now is basically buy time, so with places that we value, and people want to take care of, we put measures in place to protect them.”

There is broad consensus among scientists that even if emissions of the greenhouse gases that warm the Earth are drastically reduced, global sea levels will continue to rise for several hundred years. Sea level rise means stronger waves approach shore and faster coastal erosion.

These are the six sites that English Heritage says are most at risk:

Hearst Castle

Naval defenses are now put in place to protect Hearst Castle

Originally built by King Tudor Henry VIII between 1541 and 1544, a section of Hearst’s east wing collapsed into the sea in February 2021 after its foundations eroded. As part of the fortress defense effort, 5,000 tons of granite boulders were put into place to form a bulkhead or “reinstallation”.

Tintagel

Tintagel

Tintagel in Cornwall is closely associated with the legend of King Arthur and the Knights of the Round Table

Corrosion is not a new problem at Tintagel. It has been attacked by wind and sea since it was built in the 13th century. There are regular cliff falls and English Heritage says the funding is badly needed to repair the damage from last winter’s storms.

Bel Castle

Piel Castle in Cumbria was built to guard the Barrow-in-Furness against pirates and raiders from Scotland.

The 14th-century Piel Castle is located on a low island about half a mile off the coast in Morecambe Bay. Much of the island was lost to erosion and part of the castle fell into the sea in the 19th century. English Heritage says the castle’s forts and strongholds are now at risk of erosion and flooding.

Bayard Cove Castle

Bayard’s Cove Fort is particularly vulnerable to flooding from rising sea levels.

For 500 years, this Tudor fort in Devon guarded the narrow entrance to the Dart Estuary as a last line of defense to protect Dartmouth from naval attack.

The garrison walls were gradually built to strengthen the defenses of the Isles of Scilly after the defeat of the Spanish fleet in 1588

The shape of Garrison’s walls creates pinch points or “armpits,” where the tides are concentrated. English Heritage says these sections are highly vulnerable to erosion and will be breached in the coming years if they are not protected.

Calshot Castle

Henry VIII built Calshot Castle to defend Southampton’s approach

Calshot Castle is located on a short, weak plot of land in the Solent River. The site is low level which makes it vulnerable to sea level rise and erosion.
