BLUE GROTTO ANACAPRI ISLAND OF CAPRI

The Blue Grotto is a karstic cavity that opens on the northwest side of the island of Capri, in the metropolitan city of Naples.

Prestigious nymphoid of Roman times, after a long decline the cave became known since 1826, when it was visited by the German artist August Kopisch.

The Blue Cave has a partially submerged opening from the sea, from which it filters the outside light that - in this way - creates an intense blue tint of color, which represents the peculiar feature of the anthrax.
