Built for the Roman Emperor Diocletian at the turn of the 4th century, the palace later became the foundation of Split’s Old Town. Today, visitors can walk through Roman gates, stand in the Peristyle, explore underground cellars, climb the bell tower of the Cathedral of Saint Domnius and wander through streets where ancient walls blend into modern city life.

Why Visit Diocletian’s Palace?

Diocletian’s Palace is worth visiting because it is one of the rare ancient sites where history still feels alive. Rather than being a single monument, it is a whole neighbourhood built inside and around Roman walls.

Within a short walk, you can see imperial architecture, medieval churches, Venetian-style details, ancient columns, hidden courtyards, lively squares and the waterfront Riva promenade. It is one of the best places in Europe to experience how a Roman structure can evolve into a modern city centre.

A Roman Palace That Became a City

Diocletian’s Palace was built as a retirement residence for Emperor Diocletian, who ruled the Roman Empire before withdrawing to the Adriatic coast. The palace was part imperial villa, part military fortress and part seaside residence.

Over the centuries, people moved into the palace walls, adapted the buildings, created homes, shops, churches and streets, and gradually transformed the site into the historic core of Split. This is what makes the palace so special: it is not only preserved; it is inhabited, used and woven into daily life.

Main Features and Attractions

The Peristyle

The Peristyle is the ceremonial heart of Diocletian’s Palace. This open courtyard is framed by columns, arches, stone steps and historic façades, creating one of the most atmospheric spaces in Split.

During the day, the Peristyle is busy with visitors, guides, musicians and people passing between the palace’s main sights. At night, it becomes especially beautiful, with warm lighting, stone architecture and a relaxed open-air atmosphere.

The Palace Cellars

The cellars are one of the most fascinating parts of the palace. These underground spaces once supported the emperor’s private quarters above and today provide a powerful sense of the palace’s original scale.

The vaulted rooms, stone passages and cool atmosphere make the cellars feel very different from the sunny streets above. They are also well known to Game of Thrones fans because parts of the cellars were used as filming locations connected with Daenerys and her dragons.

Cathedral of Saint Domnius

The Cathedral of Saint Domnius is one of Split’s most important landmarks. It was built within the former mausoleum of Emperor Diocletian, giving it an extraordinary historical twist: a Roman emperor’s tomb became a Christian cathedral.

The cathedral complex includes the church, crypt, treasury and bell tower. Climbing the bell tower is one of the best ways to see Split from above, with views over the palace rooftops, the Adriatic Sea, the harbour and nearby islands.

The Bell Tower

The bell tower of Saint Domnius rises above the Old Town and is one of Split’s most recognisable features. The climb involves stairs and some narrow sections, but the view from the top is one of the highlights of the city.

From above, you can appreciate how the palace, Old Town, Riva promenade and harbour fit together. It is especially rewarding in the morning or late afternoon when the light is softer.

Temple of Jupiter

The Temple of Jupiter is another important ancient feature within the palace. Small but atmospheric, it gives visitors a glimpse into the religious life of the original Roman complex.

The temple is often visited together with the Peristyle, cathedral and surrounding streets. Its compact size makes it easy to include in a short walking route through the palace.

The Golden Gate

The Golden Gate was the main northern entrance to the palace and remains one of its most impressive gateways. Just outside the gate stands the large statue of Gregory of Nin, whose toe has become a popular photo stop and good-luck tradition.

The Golden Gate area is a useful starting point for exploring the palace because it connects the Roman layout with the city streets beyond.

The Silver, Iron and Bronze Gates

Diocletian’s Palace had four main gates, each facing a different direction. The Silver Gate, Iron Gate and Bronze Gate help visitors understand the palace’s original defensive and urban plan.

The Bronze Gate, on the southern side, connects the palace cellars with the waterfront. This makes it one of the most atmospheric entrances, especially if you approach from the Riva promenade.

The Egyptian Sphinxes

One of the most surprising details inside the palace is the presence of ancient Egyptian sphinxes. These were brought to Split in Diocletian’s time and add another layer to the site’s imperial character.

The sphinx near the Peristyle is one of the most photographed details in the palace and a reminder of the far-reaching power and collecting habits of the Roman world.

Game of Thrones Filming Locations

Diocletian’s Palace is also popular with Game of Thrones fans. The palace cellars and nearby streets were used in scenes connected with Meereen, including locations associated with Daenerys. Several Split walking tours combine palace history with filming-location stories.

Even if you are not a fan of the series, the filming connection adds another layer of interest. The same vaulted cellars and ancient stone streets that attract historians and architecture lovers also work naturally as fantasy-world settings.

Diocletian’s Palace and Split Old Town

The best way to experience Diocletian’s Palace is to treat it as both a historic monument and a living Old Town. Some travellers rush from sight to sight, but the palace is best enjoyed slowly.

Wander through narrow stone lanes, pause in small squares, look up at balconies and carved details, and follow passageways without worrying too much about getting lost. The palace is compact, and getting turned around is part of the experience.

The Riva Promenade

The Riva promenade sits just outside the southern side of the palace and is one of Split’s most enjoyable public spaces. Lined with palm trees, cafés and harbour views, it is perfect for a walk before or after exploring the palace.

In the morning, the Riva is good for coffee and people-watching. In the evening, it becomes a social promenade where locals and visitors gather beside the Adriatic.

Best Time to Visit Diocletian’s Palace

Diocletian’s Palace can be visited year-round, but spring and autumn are especially pleasant because the weather is comfortable and crowds are usually easier to manage. Summer brings long days, lively streets and warm evenings, but it can also be very busy.

Early morning is the best time for quieter photos and a calmer walk through the palace. Evening is also magical, especially around the Peristyle and Riva, when the stone glows under warm lights and the Old Town becomes more atmospheric.

How Long Do You Need at Diocletian’s Palace?

Allow at least 2 to 3 hours to explore the main sights of Diocletian’s Palace, including the Peristyle, cathedral, cellars, gates and nearby Old Town streets.

If you want to climb the bell tower, visit multiple paid sections, take a guided tour, enjoy lunch or spend time photographing the streets, allow half a day. Many travellers return several times because the palace feels different in the morning, afternoon and evening.

Guided Tour or Self-Guided Visit?

A self-guided visit works well if you enjoy wandering and discovering streets at your own pace. The palace is compact and easy to explore casually.

A guided tour is worth considering if you want to understand the Roman layout, Diocletian’s story, medieval changes, hidden details and Game of Thrones filming locations. Because the palace is layered and complex, a good guide can make the site much more meaningful.

Nearby Attractions to Add to Your Visit

Marjan Hill

Marjan Hill is one of the best places for views over Split, the harbour, islands and Old Town. It is a good addition if you want nature, walking paths and panoramic scenery after exploring the stone streets of the palace.

Split Riva

Green Market

Bačvice Beach

Bačvice Beach is within walking distance of the Old Town and is one of Split’s most popular city beaches. It is a good option if you want to combine Roman ruins with a swim.
