The Shell Grotto
Discovered in 1835, Margate's Shell Grotto is an astonishing find; 21 metres of winding passages decorated with 4.6 million shells. The walls are covered in images of gods and goddesses, trees of life and patterns of whelks, mussels and oysters. Some think it is an ancient Pagan grotto, others that it is simply an ornate Regency folly; but with no definitive explanation or history, the Shell Grotto is Kent's greatest mystery.
