The Historical Complex of Split with Diocletian's Palace in Croatia stands as an extraordinary example of Roman architecture integrated into a vibrant, living city. This monumental structure, recognized by UNESCO for its outstanding universal value, represents one of the best-preserved and most complete monuments of the Roman Empire, continually inhabited for over 17 centuries.
The Emperor's Retreat
Commissioned by the Roman Emperor Diocletian at the turn of the 4th century AD, the palace served as his retirement residence after abdicating in 305 AD. Unlike a typical palace, it was more akin to a massive, fortified Roman camp, or castrum, covering an area of nearly 31,000 square meters. Its design reflected both military and imperial residential functions, featuring defensive walls, towers, and four main gates facing the cardinal directions: the Golden Gate (Porta Aurea), Silver Gate (Porta Argentea), Iron Gate (Porta Ferrea), and the maritime Bronze Gate (Porta Aenea).
From Palace to City
After Diocletian's death, the palace did not fall into ruin but began its remarkable transformation. In the 7th century, refugees from the destroyed nearby Roman city of Salona sought shelter within its walls, marking the genesis of the modern city of Split. The palace's former imperial apartments, temples, and halls were gradually converted into houses, shops, and churches. Diocletian's octagonal mausoleum, a central feature of the imperial complex, was repurposed into the majestic Cathedral of Saint Domnius, dedicated to the city's patron saint. Adjacent to it, the well-preserved Temple of Jupiter was converted into a baptistery. The central public square, the Peristyle, still functions as a vibrant gathering place, showcasing the seamless blend of ancient heritage and contemporary life.
A Living Museum
Today, the historic core of Split is still contained within and around the palace walls, presenting an incredible urban fabric where Roman, medieval, and modern structures coexist. Walking through its narrow streets, visitors can touch history at every turn – from the ancient colonnades to the medieval bell towers, all built upon and within Diocletian's Palace. This continuous habitation and adaptation over centuries make it a unique archaeological and historical site, where daily life unfolds amidst monumental ruins, truly earning its status as a UNESCO World Heritage site since 1979.

The ruins of Diocletian's Palace, built between the late 3rd and the early 4th centuries A.D., can be found throughout the city. The cathedral was built in the Middle Ages, reusing materials from the ancient mausoleum. Twelfth- and 13th-century Romanesque churches, medieval fortifications, 15th-century Gothic palaces and other palaces in Renaissance and Baroque style make up the rest of the protected area.
Diocletian's Palace (Croatian: Dioklecijanova palača, pronounced [diokletsijǎːnova pǎlatʃa]; Latin: Palatium Diocletiani) is an ancient Roman palace and fortress complex in Split, Croatia. It was built at the end of the third century AD by the Roman Emperor Diocletian as his retirement residence. About half of the complex was for Diocletian's personal use, with the rest housing the military garrison. The complex was built on a peninsula six kilometres (3.7 mi) southwest from Salona, the former capital of Dalmatia, one of the largest cities of the late empire with 60,000 people and the birthplace of Diocletian.
Today the palace forms about half of the old town of Split, with 3,000 inhabitants and numerous shops, boutiques, cafes, bars, and restaurants. In 1979, it was listed by UNESCO as a World Heritage Site.
