Museo grotta di Tiberio, museum in Italy

Museo grotta di Tiberio is an archaeological museum in Sperlonga, built beside the sea cave that belonged to a Roman villa. It displays the sculptural groups recovered from the cave, including the blinding of Polyphemus and the Scylla group, once set around a circular pool in front of the cave. The museum also holds the villa's architectural remains and the reconstructed triclinium.

The villa was renovated during Emperor Tiberius' reign about 2,000 years ago and filled with extensive art collections. Thousands of marble fragments were discovered during coastal road construction in the 1950s, resulting in one of antiquity's major sculpture finds, prompting the museum's opening in 1963.

The cave's sculptural groups were arranged around a circular pool fed by the sea, so visitors saw the myths reflected in water. The best-known group shows the blinding of Polyphemus by Odysseus and his companions; others depict Scylla attacking a ship and the theft of the Palladium. The ensemble served the villa's seaside dining and leisure spaces.

The museum opens early each day until early evening, with extended hours from April through September, and offers affordable entry with tickets available online or at the gate. Wear comfortable shoes as the grounds have paved areas and paths to walk, and nearby parking is mainly paid during summer months.

The Pasquino group, displayed in the museum, shows a warrior carrying a fallen comrade and was long read as Odysseus rescuing Achilles' body. Scholars now link the scene to Ajax carrying Achilles, a reinterpretation that changed how the cave's sculptural program is understood.
