English Heritage has issued its Coastal Heritage at Risk report (23 September 2022). Six castles are identified as at risk. Two are in the Solent: Hurst Castle and Calshot Castle. The dramatically situated Tintagel Castle in Cornwall sustained some £40,000 worth of damage in the winter storms of 2021/22. Piel Castle in Cumbria is facing damage due to rising sea levels. The other sites are at Bayard’s Cove Fort in Devon, and Garrison Walls in Scilly.
Coastal heritage locations in East Anglia and the south-east are also facing similar pressures due to rising sea levels and extreme weather conditions. Some of the issues are explored in the EARC Heritage Report:
