This Ornate Subterranean Passageway. It Was Discovered in 1835 Whilst Digging a Pond
Margate’s Shell Grotto is an ornate subterranean passageway with walls and roof covered in mosaics made entirely of seashells. It was discovered in 1835 in the county of Kent in South East England when the head of the nearby Dane House School, James Newlove, was digging a pond into the ground.
