Grotta di Tiberio (Grotta di Nerone)

The Grotta di Tiberio, also known as the Grotta di Nerone, is a remarkable natural sea cave located on Via Flacca, just south of Sperlonga. Originally transformed by Emperor Tiberius into a monumental dining hall for his villa, the site is now an integral part of the National Archaeological Museum of Sperlonga. The cave opens directly onto the sea and features a central circular pool, or peschiera, where the platform for the triclinium (dining area) was once situated.

The walls of the grotto display large sculptural groups depicting episodes from Homer’s Odyssey, including Scylla attacking a ship, the blinding of Polyphemus, and the theft of the Palladium. These statues were discovered in 1957 and are considered masterpieces of Hellenistic art. The site is an archaeological zone rather than a beach, offering a unique blend of natural beauty and ancient history.

Access is via the coastal road, with no dedicated public parking available, though private paid lots exist nearby. Visitors with motor disabilities can request gate access for parking. The grotto is typically visited in conjunction with the museum’s sculptural groups, providing a comprehensive understanding of the imperial villa’s artistic legacy. While specific opening hours and admission fees are not detailed in the provided research, it is advisable to check the official museum website for current schedules. The experience of visiting the Grotta di Tiberio offers a profound connection to Roman imperial history and the artistic achievements of the era.
