Cellars

Overview

Deep beneath the bustling streets of Split, Croatia, lie the remarkable Cellars of Diocletian’s Palace, often referred to as the 'substructures' or 'basement halls'. Located at the southern end of the ancient Roman complex, these vast vaulted chambers are among the best-preserved ancient structures of their kind in the world. Originally designed to elevate and support Emperor Diocletian's lavish imperial apartments above, they also served as crucial storage areas for supplies like food and wine. Today, these historical depths offer visitors an extraordinary glimpse into Roman engineering and daily life, functioning as a popular tourist attraction, a marketplace for local artisans, and a venue for cultural events.

The Cellars' enduring appeal stems from their structural integrity and their ability to vividly illustrate the grandeur of the palace that once stood directly above. As you descend into these ancient halls, you are stepping into a foundational piece of Split's history, a place where time seems to stand still.

History & Cultural Background

Construction of the Cellars began in the late 3rd century AD, as Emperor Diocletian meticulously planned his retirement residence in his native Dalmatia. The primary architectural purpose of these substructures was ingenious: to compensate for the natural slope of the terrain, effectively leveling the ground to create a stable foundation for the emperor's private quarters and residential complex. Consequently, the layout of the Cellars faithfully mirrors the design of the rooms that existed directly above them, providing invaluable insights into the palace's original architecture which has largely been lost or transformed over centuries.

Following Diocletian's death and the decline of the Roman Empire, the palace underwent significant changes. In the early Middle Ages, parts of the Cellars were even used as residential spaces by refugees seeking shelter within the palace walls. Over time, however, these underground halls were gradually filled with debris, sewage, and waste from the medieval city that developed above. While this might seem like neglect, this unintentional burial ironically served as a protective cocoon, preserving the structures from further damage and the ravages of time.

The rediscovery and excavation of the Cellars commenced in the mid-19th century, spearheaded by figures like architect and conservationist Vicko Andrić. Extensive restoration efforts continued into the 20th century, with parts of the western halls opening to the public in 1959, and the eastern sections following much later in 1996 after thorough archaeological work.

What Makes It Special

What makes the Cellars truly special is their remarkable state of preservation and their architectural ingenuity. They represent one of the world's best-preserved examples of Roman substructures, offering a tangible connection to the advanced engineering skills of the 4th-century Romans. The intricate barrel-vaulted ceilings and robust stone walls are a testament to the meticulous planning and construction that ensured the stability of the imperial residence above.

The Cellars are also unique because their ground plan perfectly replicates the now-vanished imperial chambers directly overhead. This 'mirror image' allows historians and visitors alike to visualize the grandeur and layout of Diocletian's private living quarters, which were largely demolished or integrated into later medieval buildings. Furthermore, their role as a filming location for HBO's 'Game of Thrones,' serving as Daenerys Targaryen's dragon lair, has cemented their place in popular culture, drawing a new generation of curious travelers.

Stories, Fun Facts & Local Details

Among the many fascinating details of the Cellars, the 'Game of Thrones' connection stands out. Fans of the epic series will immediately recognize the main hall as the dramatic setting where Daenerys kept her dragons in Meereen, adding a layer of contemporary allure to its ancient mystique.

Historically, the Cellars weren't just for structural support; they were vital for the palace's daily operations. Remnants of large presses used for wine and olive oil production are still visible today, reminding us that Emperor Diocletian likely enjoyed local Dalmatian wines produced right within his palace walls.

An intriguing local detail concerns the acoustics of certain chambers. Legend has it that a circular room, located directly beneath what was once the emperor's bedroom foyer, possessed unique echoing properties. Diocletian, known for his paranoia, specifically requested this feature so that any approaching footsteps could be heard, providing an early warning system against intruders. This clever design detail is said to have contributed to his peaceful retirement and successful abdication.

The southern Brass Gate (Porta Aenea) originally opened directly from the sea, allowing ships to deliver goods and supplies straight into the Cellars, highlighting the palace's strategic coastal location and its self-sufficient design.

Visitor Perspective

Stepping into the Cellars offers a truly immersive and atmospheric experience. The transition from the sunny Riva promenade or the bustling Peristyle into the cool, dimly lit stone chambers is like stepping back in time by seventeen centuries. The air is noticeably cooler underground, providing a welcome respite from Split's summer heat.

Visitors can wander through vast, open halls and explore smaller, labyrinthine passages. While some areas host a vibrant market selling local souvenirs and crafts, other sections remain quieter, allowing for a contemplative journey through ancient history. You can access the Cellars either from the Riva waterfront through the Bronze (Brass) Gate or by descending a staircase from the Peristyle, the central square of the palace. Allowing 45-60 minutes for an unhurried visit is recommended to truly appreciate the intricate details and absorb the historical significance of this extraordinary underground world.
