Located on the Dalmatian coast in southern Croatia, Split is the second largest city in Croatia. Split has an interesting historic core centred around the Diocletian palace, a UNESCO World Heritage Site with an area of 160m x 190m. In Roman times this was a Roman palace built in the 4th century AD, which was later partially destroyed and covered with other buildings. Split was first settled in the 4th century BC and became a free city during the middle ages. Nowadays it acts as a hub to the neighbouring islands.
