• We went to the Shell Grotto, a mysterious subterranean passageway covered in a mosaic of seashells.
• 
• It was discovered in 1835 and nobody knows why it's there. It was so much bigger than I thought it would be.
• 
• The grotto was so pretty inside and it was fun looking for all the shapes and designs in the mosaic.
