We embark on a journey to uncover the hidden marvels that lie beneath the bustling streets, the captivating Diocletian Palace Substructures. For centuries, this remarkable underground world has remained shrouded in mystery, and it is our privilege to reveal its secrets to you.

Our adventure begins at the heart of Split, where the majestic Diocletian Palace stands proudly, a Unesco World Heritage site since 1979. Built by the Roman Emperor Diocletian in the 4th century AD, the palace served as a grand residence and a testament to the emperor’s power. But it is what lies below that truly captivates the imagination.

Descending into the substructures, we step back in time, as if transported to a different era. As we walk through the dimly lit passages, you will feel the ancient stones whispering their tales of bygone empires and tumultuous history. These substructures, ingeniously designed, provided the foundation for the palace above and served a variety of purposes, from storage rooms to intricate heating and cooling systems.

Marvel at the impressive architecture that has withstood the test of time, and learn about the skill and craftsmanship of the Roman engineers who constructed this labyrinthine network of rooms. The perfectly carved stone walls, vaulted ceilings, and ornate columns will leave you in awe, as you ponder how such an ambitious project was realized so long ago.


Our expert guide will narrate fascinating stories of Emperor Diocletian’s life, his reign, and the subsequent transformations of the palace throughout the centuries. Discover how the substructures were repurposed, adapting to different historical periods, including medieval times, when the people of Split sought refuge here during invasions and upheavals.

Be prepared to uncover the secrets of these underground passages, as we reveal hidden alcoves, forgotten chambers, and even an ancient baptistery. You’ll learn about the significance of these discoveries and their implications for understanding the historical context of Split and the surrounding regions.

As we meander through the cool shadows, keep an eye out for the unique openings that allow glimpses of natural light. The play of light and shadow creates an ethereal ambiance, making this underground excursion even more enchanting.
