Diocletian's Palace is the historic heart of Split and one of the best-preserved Roman palaces in the world. It was built in the 4th century for the Roman Emperor Diocletian, who chose this area to spend his retirement. Today, the palace is not a museum but a living part of the city. Within its ancient walls you’ll find homes, cafés, shops, and narrow stone streets filled with everyday life. Walking through the palace feels like stepping into different time periods at once—Roman foundations, medieval additions, and modern Split all blending together in one unique space.
