Palace built
c. AD 295–305
The palace the Roman emperor Diocletian built for his retirement around AD 295–305, which grew into the old town of Split. About half of it was for the emperor, the rest for his garrison. Today some 3,000 people live inside.
The cathedral was built in the Middle Ages from the materials of Diocletian's mausoleum. Romanesque churches, medieval walls and Gothic, Renaissance and Baroque palaces fill the rest of the protected area.
