Ancient palaces and historic towns
Diocletian’s Palace was built as the emperor’s fortified retirement residence on the Dalmatian coast. Its enclosure contained streets, gates, ceremonial spaces and residential quarters. The main north–south street led from the Golden Gate towards the Peristyle, while an east–west route divided the complex into northern and southern sectors.
Later occupation incorporated the palace into the fabric of Split. The emperor’s mausoleum became the cathedral, and subsequent buildings occupied spaces within the Roman walls. The surviving gates, masonry and street alignments therefore belong to a large ancient complex that continued to shape an inhabited town.
Roman amphitheatres
Pula Arena preserves the extensive outer wall of a Roman amphitheatre. Its limestone arcades rise around an elliptical arena, with rectangular openings at the upper level. The sloping site means the sea-facing side exposes more storeys than the uphill side.
Stairways and entrances distributed spectators around the seating, while projecting exterior towers contained paired stairs serving the upper levels. The repeated arches are thus part of the building’s circulation and support system. They preserve the scale of a purpose-built arena whose construction and enlargement took place during the first century, even though its original seating arrangement has not survived in full.
Castles and coastal fortresses
Klis Fortress follows a rocky pass between the Mosor and Kozjak mountains above Split. Three successive defensive lines lead towards the highest strongpoint. The irregular walls fit the rock, and the principal approach enters from the lower western side. Its long sequence of defended spaces reflects the terrain and the need to control movement between the coast and the interior.
Nehaj Fortress at Senj is concentrated within an almost cubic sixteenth-century building. Thick walls taper upwards through three defensive levels, and projecting corner structures allow fire along the wall faces. A further projection protects the entrance. Its compact plan places the principal defensive positions within one block, in contrast to the extended ridge system at Klis.
Churches and cathedrals
The Church of St Donatus in Zadar was completed in the early medieval period on part of the Roman forum. Its cylindrical body contains a central space surrounded by an ambulatory, with a circular gallery above. Large piers and reused Roman columns support the inner structure, while three apses project towards the east. Roman material became part of a new religious building with a very different plan.
Šibenik Cathedral has a nave, aisles, three apses and a dome over the crossing. Its carefully cut stone slabs use overlapping and interlocking joints, with ribs, piers and arches incorporated into the structural system. Carved portals add another use of the same material: the Lion Gate includes figures of Adam and Eve above sculpted lions. The building brings architectural support, enclosure and detailed sculpture together in stone.
