The Blue Grotto is one of Capri’s most visited sites, famous for its brilliant blue color luminescence. The sapphire light comes from the sunlight entering through two sources, a small hole precisely at the waterline and one directly below the waterline. The light is filtered by the water which absorbs the red tones, leaving only the azure ones to pass into the cave.

Grotta di Nereo
The Grotta di Nereo is the largest underwater cave in the Mediterranean. It is located on the north-west side of Sardinia, at a few kilometers of Alghero, beneath Capo Caccia. Because the cave is so vast with many openings and two main entrances, the honor of its discovery is disputed between several divers who discovered the cave separately in 1957.
