The most prominent English castle experiencing significant loss to the sea is Tintagel Castle in Cornwall, famous for King Arthur legends, where large parts of the island stronghold have fallen into the sea since medieval times due to constant coastal erosion. Another key example is Hurst Castle, a Tudor fort in Hampshire, where a section of its 19th-century wing collapsed into the ocean in 2021, leading to major preservation efforts.

I think the Ness of Brodgar has been slipping into the sea for a long while (it was even before anyone knew it was there) and excavations had wrapped up. Now apparently it's going to be reopened because of 'geophys' studies made subsequent to the closing of the site.

Why are Time Team going to be digging at The Ness of Brodgar in 2026? 

Be careful what you wish for. 

It must have been a very good night in the pub when the Ness of Brodgar archaeological team decided - after field work had ceased and the site had been backfilled in 2024 - that it would be a good time to conduct a thorough magnetometry resistivity and Ground Penetrating Radar survey of the site. 

20 more years of data anyone? Plus an inexplicable anomaly that just has be excavated? They're going to need a bigger boat!
