@6:50 [quizzically, dramatic music] “What was the harpoon doing in the middle of the North Sea?”
Oh for Pete’s sake! LOL
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.
The Brits are leaving things all over the place
