#1 of 12 Nature & Parks in Margate
... this grotto is largely formed underneath a residential garden in a normal looking street but it is amazingly decorated with 4.3 million shells in intricate patterns - a real gem hidden in the depths of the earth.
You walk in through it and they have a whole selection of shells to take home as souvenirs, and some really cool Margate memorabilia, postcards, and a load of beachy seaside souvenirs.
