These conical grids keep humans and animals from falling down the mine shafts and allow the bats that roost in them free comings and goings! A very sensible idea.

Nice composition! Nice way to protect the bats =) And the odd above ground critter ;)

Exactly! Whoever thought of it, deserves a medal. Before, they simply blocked the entrance up with steel and concrete, with dire consequences for the bats.

That's cool. A propper cave with upward going exit like batman!
Here the bats must live mostly in black appartment box units made from wood concrete and hung somewhere at the forest edge just for them.

Well, man made mine shafts rather than natural caves, Sonia but all the same to a bat!

Andy, this is amazing and interesting! I would love to see the bats coming and going! What type of mines were they?

Thank you, BJW.

I never saw any bats here!

I wasn't allowed out on the cliff tops after dark! :o)

Tin, in the main, with some copper and arsenic. Cornwall was the world centre of tin supply in the 18th and early 19th centuries.
