Split is the second-largest city of Croatia after the capital Zagreb, the largest city in Dalmatia and the largest city on the Croatian coast. It lies on the eastern shore of the Adriatic Sea and is spread over a central peninsula and its surroundings. An intraregional transport hub and popular tourist destination, the city is linked to the Adriatic islands and the Apennine Peninsula.
The city was founded as the Greek colony of Aspálathos in the 3rd or 2nd century BCE on the coast of the Illyrian Dalmatae, and in 305 CE, it became the site of the Palace of the Roman emperor Diocletian. It became a prominent settlement around 650 when it succeeded the ancient capital of the Roman province of Dalmatia, Salona.
