The story of Split is already 17 centuries old, dating to the time the Roman Emperor Diocletian decided to build his Palace right on the peninsula near the great Roman city Salona, where he wanted to spend the last years of his life. During these 1700 years the Palace slowly turned into a city, which to this day lures with its rich tradition, glorious history and beauty of its natural and cultural heritage.
Diocletian Palace and the entire historical core of Split have been on the World Heritage UNESCO list ever since 1979, and not only for the extraordinary preservation of the Palace, but also because the Palace and its city (or the city and its Palace, if you like) continue to live a full life. All historical layers from the old Rome, middle ages till today are still visible and alive in this structure. A walk through the ancient city takes you through time, along the great examples of ancient architecture like Peristyle, the middle aged Romanesque Church and Gothic Palace, Renaissance portals of the noblemen’s houses, Baroque facades and modern architecture superbly merged in the rich heritage.
Such stratification is mirrored in everyday life of Split. Local inhabitants sit in the same cafes, restaurants, shop in the same stores as tourists, giving them the impression that, by arriving to Split, they became a part of the city and its rhythm. The vegetable market and the fish market represent the centre of each family’s life in Split, just as the entire social life of this city of 200 thousand reflects on the Riva (waterfront), where every guest should endeavour to have his coffee alongside noisy, temperamental folk of Split.
