Diocletian's Cellars: A Subterranean Journey Through Roman History

Delve into the depths of Diocletian's Palace with a visit to its cellars, also known as the substructures. This underground complex represents one of the best-preserved ancient structures of its kind in the world. Constructed in the 4th century AD, these massive barrel-vaulted cellars served two primary purposes: to elevate the imperial residential area above and to function as storage space for the palace.During Roman times, these cellars were used to store foodstuffs and wine. A remnant of a large press used in wine production is still visible today. The cellars are a structural replica of the chambers above, enabling historians to reconstruct the layout of the emperor's private residence. In the early Middle Ages, parts of the cellars were repurposed as residential areas. Over time, they were used as waste pits before being rediscovered and excavated in the 19th and 20th centuries.Today, the cellars are open to the public, offering a unique perspective on Roman architecture and history. Visitors can explore the labyrinthine rooms and halls, which host art exhibitions, theater plays, and cultural events. The central hall features souvenir stalls, while other areas showcase the cellars' original Roman design. The cellars are accessible via the Bronze Gate on the Riva or through stairs from the Peristyle.
