Ivan Konstantinovič Ajvazovskij, La grotta Azzurra (1841)

The blue grotto (grotta azzurra in Italian) is a sea cave located on the northwest coast of the island of Capri, in the municipality of Anacapri. It is famous for its clear water and its bright blue reflections that come from the external light reflected by its walls and whose red component is filtered by the water.
It is this blue color which gives this cave its particularity and which made it the most famous attraction of Capri. One visits it by a small rowboat, lying down to pass the entrance. It is forbidden to swim in the cave (although some do it after the closure of visits)

Under the Roman antiquity, it was a nymphaeum, a sanctuary dedicated to the aquatic nymphs of mythology. Subsequently, the blue cave was long avoided, considered a cursed place. It was in 1826 that it was rediscovered by the fisherman Angelo Ferraro who accompanied the German painter August Kopisch (1799-1853) and the Swiss artist Ernest Fries (1801-1833). Since then, it has become a stage of the “grand tour” in Italy.

This karstic underground cavity is about 60 m long and 25 m wide, with a depth of about 13 meters, the bottom of which is sandy. The ceiling rises from 7 to 14 meters. The entrance is 2 meters wide and only 1 meter high.
