The Shell Grotto in Grotto Hill, Margate, Kent is one mystery that has never been solved. Even the great Poirot himself probably could not answer; who made it, why they made it and when?
A subterranean wonder 31.5 metres long consisting of some 4.6 million shells, discovered in 1835 and nobody knows anything about it. Fascinating.
The walls and ceiling are adorned with whelks, oysters, cockles and mussels depicting a myriad of shapes, symbols and patterns. It's up to the individual to interpret them as they wish.
Much conjecture has been bandied about the grotto. Folly, secret shrine or private place of worship are just a few of the ideas of its purpose.
Discovered during house renovations which sat atop, maps of the time showed no reference to the passage ways. It was just there.
For me, it is a great way to spend 45 minutes or so being amazed at the work, skill and thought process that produced this wonder. In a way, it might be a shame if its origins were known.
