The grotto was used as a triclinium, an ancient Roman dining room, where the emperor and his guests reclined over the water.
Fragments of the 'Scylla' and 'Polyphemus' marble groups were found shattered into thousands of pieces in the grotto's pool.
The sculptures were attributed to the same Rhodian artists responsible for the Laocoön and His Sons.
The villa featured a series of interconnected fish ponds, or vivaria, that allowed the Romans to farm fresh seafood.
The grotto was essentially a natural cave modified with masonry to enhance its acoustic and visual connection to the sea.
The site was abandoned and eventually collapsed following a series of landslides and seismic events.
Excavations in the mid-20th century were sparked by the construction of the modern Via Flacca road.
The museum is built specifically to display the sculptural fragments in the order they were hypothesized to exist within the grotto.
Villa di Tiberio is an extensive Roman seaside imperial estate located on the Tyrrhenian coast in Sperlonga. The site encompasses the remains of Emperor Tiberius's residence, including a residential complex and a natural grotto used for hosting lavish banquets. The adjacent National Archaeological Museum houses significant marble sculptural groups recovered from the grotto's pool. These sculptures depict episodes from the Odyssey, including the blinding of Polyphemus and the ship of Odysseus. The complex was heavily expanded in the 1st century AD and represents a fusion of Roman architecture and natural geological features. Excavations have revealed sophisticated hydraulic systems designed to integrate the sea into the villa's design. The site serves as both an open-air archaeological park and a climate-controlled museum for fragile artifacts. It is situated directly along the Via Flacca, providing direct access to the coastline where the grotto sits.

Visit the museum before walking down to the grotto ruins to better understand the context of the sculpture fragments.
Wear footwear suitable for walking on uneven, sandy, or dusty archaeological paths.
Bring sun protection, as the path from the museum to the grotto is largely exposed with minimal shade.
Do not attempt to swim directly inside the grotto area, as it is a protected archaeological zone.
Closed on Mondays; often experiences reduced operation or closures during winter months.
Maintain silence inside the museum and do not climb on or touch the archaeological ruins.
