There are thousands!
Here is one of my favourites - called Sevendroog Castle. It isn't a castle - and Sevendroog is apparently somewhere in India - it was built by some raving English loony in the middle of some woods near Blackheath in London.
It just sits there. Useless but thought provoking - which is precisely what all follies should be.

That should have been Severndroog Castle - Severndroog with an R rather than Sevendroog.
The National Trust manages a shed-load full of follies. Google advance - key in - National Trust folly.

Forgot to mention that Severndroog Castle is also triangular.
Why triangular? I suppose if you are going to buld a folly you might as well go all the way.

Sorry - got a new laptop and the mousepad is so sensitive it posts a comment to Lycos if I as much as look at it.
Was in the middle of editing - should have been West Wycombe not High Wycombe - also known as the West Wycombe Caves.

I give up! This laptop is barmy! At least the pic is the one I wanted to show you.
I was trying to say: If it is 'cave follies' you are particularly interested in, take a look at the Hell Fire caves at West Wycombe.
Also known as the West Wycombe Caves and as Sir Francis's Folly...
Rumour, mystery, and wild allegations of drunkenness and debauchery surround the history of the 'Hell-Fire' caves - a labyrinth of caverns and tunnels, which runs a quarter of a mile into the hill under West Wycombe Park.
The caves were excavated in the 1750s for the 2nd Baronet Sir Francis Dashwood of West Wycombe Park, but opinion differs as to the reason.
