Emperor Claudius' sunken nymphaeum

This sunken structure was a large rectangular hall with a semicircular end decorated in marble. The building lies deep beneath the sea surface and can only be reached underwater.

The structure was built in the middle of the first century during a Roman emperor's reign. It later sank due to natural changes of the coastline in this volcanic region.

The statues inside depicted mythological scenes that are now kept in a nearby castle museum. Visitors can understand the artistic traditions of the ancient world through these surviving works.

This site lies several meters below the sea surface and can only be visited with special equipment or glass-bottom boats. Plan a water-based visit to see this location.

Sea plants and natural coral formations have grown over the ancient Roman walls. This blending of old history and living nature makes the place unusual.
