Diocletian's Palace

Brief information

The Roman Palace of Diocletian became not a closed-off ruin, but part of a living city. The emperor built his residence by the Adriatic near Salona and, after his abdication, lived here, already outside high politics. Later, the meaning of the walls changed: residents of Salona moved onto the palace grounds, and the former imperial residence became a protective space.

Because of this change, the palace is read not as a single monument, but as a city within an old Roman framework. Today the complex occupies a large part of Split's historic center; inside are residential buildings, restaurants, shops, and hotels. The strongest shift is visible in the former sacred places: Diocletian's mausoleum was rebuilt as a Christian cathedral, and the Temple of Jupiter as a baptistery.

What to notice right away

The main principle of the visit is to compare the military clarity of the plan with the later urban life inside it. The rectangular form and two main streets crossing the inner courtyard at right angles recall the layout of a Roman legionary camp. Powerful walls up to 20 meters high and the three surviving towers show why the palace could later function as a refuge, and not only as a ceremonial residence.

It is worth noticing how different parts of the complex changed their purpose. The southern facade with its colonnade faced the sea bay, with the imperial chambers nearby. The mausoleum became a Catholic cathedral, the Temple of Jupiter a baptistery, and at the end of the 16th century the cellars were adapted as commercial warehouses. The materials also speak to the scale of the design: brick, limestone from Brač, and tuff are combined with marble, granite columns, and sphinxes brought from afar.
