Discovered in 1835, the Shell Grotto is an incredible underground network, consisting of mosaics made entirely from sea shells. The Grotto has been the subject of much speculation over the years and is still a mystery today as to why it was created and the purpose it served. After two years of being found in 1835, the Shell Grotto was opened to the public in 1837.
The Shell Grotto is approximately a 6 minute drive (12 minute walk) from the Margate Harbour Arm
