Diocletian's Palace

Diocletian’s Palace stands in the heart of Split, Croatia, on a short peninsula six kilometres southwest of Salona. Built at the end of the third century AD as the emperor’s retirement home, it was also a heavily fortified military base. Half of the complex served Diocletian while the rest housed soldiers. The palace sits on white limestone from Brač and tufa from nearby riverbeds, with bricks made in Spalatum. Its ground plan forms an irregular rectangle with sixteen projecting towers and four corner bastions. The design follows Roman fort models like Castrum Divitia across the Rhine. The palace is worth visiting because it remains one of the world’s most complete Roman palace ruins. UNESCO listed the old town of Split, which grew inside the palace walls, as a World Heritage Site in 1979. After Salona fell to invaders in the seventh century, refugees rebuilt their lives within the strong walls. Later, medieval houses filled Roman buildings and streets, and the Cathedral of Saint Domnius reused Jupiter’s temple and Diocletian’s mausoleum. In the 18th century, Scottish architect Robert Adam published measured drawings that inspired Neoclassical design across Europe. Visitors walk along Roman streets lined with medieval shops and cafes. The cathedral’s bell tower rises above Diocletian’s former tomb, while basements still hold homes and businesses. The palace’s southern façade faces the sea, offering views of the Adriatic. Inside, the Peristyle courtyard shows original columns and sphinxes brought from Egypt. Statues and carvings recall the emperor’s vanished companions. The mix of Roman stone and later life shows how the palace has been lived in for fifteen centuries.
