Blue Grotto

Azure coastal hollow

Blue Grotto is a sea cave on the coast of Capri, Italy, famous for its luminous blue light caused by sunlight passing through an underwater opening.

The name applies to similar caves elsewhere: We visited the Blue Grotto in Malta.

Any dramatically lit underwater cavern may be called a blue grotto.
