Grotta Azzurra

The Blue Grotto is a sea cave on the northern coast of Capri, within Anacapri. Its luminous blue water is the best-known feature of a place that also preserves evidence of Roman use as a nymphaeum.

Why it matters

Natural light and imperial-period archaeology give the cave a double identity. Roman sculptures recovered from its waters show that this dramatic marine setting was incorporated into the island's ancient landscape of leisure and display.

What to notice

Sunlight entering through the opening at the waterline produces the blue illumination inside the cavern. Its intensity changes with light and sea conditions. Surviving Roman cement-work remains add a quieter material trace of the nymphaeum to the spectacle of the water.

Context and history

The ancient decorative group included Neptune, Tritons and a draped female figure. Underwater recovery campaigns between 1964 and 1975 brought sculpture back to light. Above the cave are villa remains traditionally associated with Tiberius. In 1826, August Kopisch and Ernst Fries helped introduce the grotto to a wider European audience, beginning a new chapter in its artistic and literary reputation.
