Split (Croatian pronunciation: [splît]) is a Mediterranean city on the eastern shores of the Adriatic Sea, centred around the ancient Roman Palace of the Emperor Diocletian and its bay and port. With a population of 178,192 citizens, and a metropolitan area numbering up to 467,899, Split is by far the largest Dalmatian city and the second-largest city of Croatia. Spread over a central peninsula and its surroundings, Split's greater area includes the surrounding seaside towns as well. An intraregional transport hub, the city is a link to numerous Adriatic islands and the Apennine peninsula, as well as a popular tourist destination.

Split is also one of the oldest cities in the area. While it is traditionally considered just over 1,700 years old counting from the construction of Diocletian's Palace in AD 305, archaeological research relating to the original founding of the city as the Greek colony of Aspálathos (Aσπάλαθος) in the 6th century BC, establishes the urban tradition of the area as being several centuries older.
