Diocletian’s Cellars : info and guided tour

Introduction to Diocletian’s Cellars

The Cellars of Diocletian are located beneath Diocletian’s Palace, in the heart of Split’s old town. This underground complex was part of the Roman imperial residence and mirrored, below ground, the layout of the rooms above. Today, it is among the best-preserved ancient remains in the city.

The space stands out for its massive vaults, stone corridors, and regular rooms, which reveal the solidity of Roman architecture. The underground volumes were used in particular to support the imperial apartments and structure the upper level. Their layout helps to understand the original shape of the palace and its monumental use.

The cellars are famous because they offer direct access to Split’s historic heart and the city’s Roman heritage. They also have strong cultural value, as they are part of the living urban fabric of the old town. Some areas now host passageways, exhibitions, or craft activities.

Among the emblematic features to see are the large vaulted halls, the thick stone walls, and the succession of spaces that outline the palace’s underground level. The listed address, Ul. Iza Vestibula 3, places the site immediately next to the vestibule and the palace’s main entrances, in a very busy area of Split.
