This strange, underground grotto was discovered in 1835. It was opened to the public in 1838 and is now a Grade I listed building which remains a tourist attraction. Although there are many theories on the Grotto's origins, who made it, when or why remain mysteries. It contains 4.6 million shells (I wonder who counted them) and, although in need of cleaning, a way of doing this without destroying the shells has yet to be discovered.
