Split lives on its tourism, further on fishing, wine and its paper, concrete and chemical industries. It is also an important traffic point for Dalmatia: most of the middle Dalmatian islands (Brač, Hvar, Šolta, but also Vis or Lastovo which are further away) are not reachable except through Split's harbour, and its airport is often the first stop for most of the tourists to this region.
Split is known for Diocletian's Palace and its Dome. Up to this day Split is the seat of an archbishop. Despite the existence of the ancient Salona (today Solin) just north of today's Split, the construction of the palace marks the beginning of the city: emperor Diocletian ordered it built around 300, and in the 7th century - the giant building was long deserted - the first citizens of Split settled inside its walls. Even today the palace constitutes the inner city of Split, full of shops, markets, places and the dome, that was a temple in Diocletian's day.
After that, Split belonged a long time to Venice (in the 14th century and then from 1420 on), until it fell to Austria-Hungary in 1797. The province Dalmatia was later joined with Croatia and Split remained in Croatia (at times as Yugoslavia) until the present day.
