Diocletian's Palace, the No.1 must-visit in Split, is a time capsule of the Roman Empire! 4.5 points, 65 reviews. This 4th-century palace is now inhabited by residents and small shops, and the walls hide thousands of years of stories. Stepping into the bronze gate, on one side is the solemnity of the Roman colonnade, on the other side is the bustle of the market, churches, mausoleums, and atriums, where history and life collide everywhere. Free admission, but don't miss the guided tour, listen to the retired life of the Roman emperor, and see how Croatians make ancient monuments a daily life, a super cool time and space interweaving experience
