The Blue Grotto, or Grotta Azzurra, is a world-famous sea cave on the island of Capri, Italy, renowned for its enchanting, glowing blue waters. This natural phenomenon occurs when sunlight enters through a small underwater cavity and is refracted, illuminating the cave with an ethereal azure hue. Measuring around 60 meters long and 25 meters wide, the grotto is accessed by small rowboats that navigate its narrow entrance, a thrilling experience in itself.
Steeped in history, the grotto was used as a personal swimming pool by Roman Emperor Tiberius in ancient times. Its unique allure was rediscovered in the 19th century, drawing travelers and artists alike. Today, it is a top attraction on the Amalfi Coast, captivating visitors with its magical atmosphere. To fully appreciate its charm, visits are recommended on sunny days when the light displays are most vivid. The Blue Grotto is a testament to nature's unparalleled artistry.
