Taken back in 2020 this is a number of caves in Pleasley Vale, Nottinghamshire where I used to live. Thought it would be good for the Architecture challenge so dug it out, the photo not the cave!
@wakelys Ha! Ha! But it (and others in the area) are very interesting with quite a history of use for various functions, during WWII they were used for ammunition dumps. There is also very strong local evidence that one of them went all the way to a church just over a mile away and came out in its cript.
