Blue Grotto: photo description (Grotta Azzurra)

The blue Grotto is a sea cave on the coast of the island of Capri, one of the main natural attractions of the island. Sunlight, passing through a maze of caves and refracted in the water, creates a blue reflection that illuminates the cave. The grotto is 60 meters long, 25 meters wide and 150 meters deep, ending a sandy bottom. The entrance to the cave is two feet wide and about a meter in height, for this reason you can only get in during low tide and dead calm at sea. And to get inside, tourists should go on the bottom of a small four-seater boats, which tie with metal chains nailed to the walls of the cave that leads inside. Swimming in the cave is prohibited for reasons of safety and to preserve the purity of the water.

The blue Grotto is one of the few caves in the world that literally glows blue or emerald light. This effect arises from the fact that the light in the cave comes from the two holes - small holes in the wall exactly at the level of the water (about half a meter in diameter) and large holes are located directly under the cave entrance. Passing through the water, the red spectrum of sunlight is reflected, and the blue is inside.

In the era of Ancient Rome, the Blue Grotto was used as a private swimming pool of Emperor Tiberius, and was also a kind of sea temple. Tiberius moved to Capri from Rome in 27 BC In his reign, the grotto was decorated with several statues, and at the edge of the cave was equipped with a relaxation area. Three ancient Roman statues of sea gods Neptune and Triton was discovered at the bottom of the grotto in 1964-m to year - they are on display in the Museum in Anacapri. Probably those statues that were described by the Roman historian Pliny the Senior in the 1st century BC In 2009-m year, was discovered seven pedestals for statues, and it says that 4 more statues lie at the bottom of the cave. Today, the local Association "Marevivo" has plans for the reconstruction of the Blue Grotto in its original form by installing copies of antique statues at the same places where they stood when Tiberius. The project is implemented in cooperation with the archaeological Institute of Pompeii.

At the rear of the main caves of the Blue Grotto located three passes in the so-called Hall of Names (Hall dei Nomi), whose walls are covered with names and signatures of visitors to the caves over hundreds of years.

Interestingly, in the 18th century sailors and residents of Capri avoided to be near the Blue Grotto, because it was believed that it is inhabited by witches and monsters. The cave was opened to the public only in 1826, the year two German estelami, who later described the visit to the grotto. Been here and the famous American writer mark TWAIN, and Alberto Moravia.
