We were pottering along through the Norfolk countryside when we found this tower.
Fortunately there was a notice to give us a clue.
It seems that it fell into disrepair, was rebuilt in the 19th Century and again fell into disrepair, being pulled down in 1969. It was reputedly used by Satanists, struck by lightening (which may or may not be connected) and restored again.
It’s an interesting place, and well-looked after, but there isn’t much to keep you, not even an information board. Fortunately there is plenty about it on the internet.
Interestingly, some of the gravestones show the same names as the war memorial. The continuity of the countryside is an amazing thing.
