A 3rd-century Roman emperor's retirement complex that has been continuously inhabited for 1,700 years — today containing restaurants, apartments, boutiques, bars, and the Cathedral of Saint Domnius in Diocletian's own mausoleum.
Why It’s Worth Your Time
Diocletian's Palace (built 295–305 AD, covering 38,000 square meters) is the defining Croatian attraction — not because it is merely old, but because it is alive. Emperor Diocletian retired here at the end of his reign and the palace was built to the specifications of a small city: four gates, colonnaded streets, a central Peristyle (the ceremonial courtyard), the Imperial Apartments, and the Mausoleum (where Diocletian himself was buried, converted into the Cathedral of Saint Domnius within 300 years — the most Croatian historical irony). The palace was never abandoned: after Rome's fall, refugees from Salona (the Roman provincial capital destroyed by Avars in 614 AD) moved into the palace and have been there ever since. Today it is the most concentrated mixture of Roman, medieval, Renaissance, and modern urban life in Europe.
What Stands Out
- Built 295–305 AD — continuously inhabited 1,700 years
- Cathedral of Saint Domnius — in Diocletian's own mausoleum
- The Peristyle — venue for klapa singing
- The Vestibule — Roman dome open to the sky
- UNESCO World Heritage Site
