Split

Split is not a city with Roman ruins — it is a city built inside a Roman ruin. Diocletian’s Palace, constructed in the fourth century as a retirement home for the emperor, was never abandoned. Instead, people moved in and never left. Today the palace walls contain apartments, restaurants, shops, and a cathedral built inside Diocletian’s mausoleum, creating a layered archaeological puzzle that is also a functioning neighborhood where someone’s grandmother lives above a Roman basement.

The Peristyle — the palace’s central courtyard — is where the layers collide most visibly: Egyptian sphinxes, Roman columns, a medieval bell tower, and modern cafe tables all share the same sunlit square. Outside the palace, the Riva waterfront promenade is Split’s social stage — locals promenade in the evening, ferries depart for the islands, and the setting sun turns the palace walls amber. The Marjan Hill peninsula, a ten-minute walk from the center, offers pine-shaded trails, hidden swimming coves, and chapel viewpoints overlooking the city and the islands beyond.

When to go: May to June or September for warm weather and ferry access to the islands without peak-season crowds. Split is a year-round city at heart.
