Explore the atmospheric and historical center of Split in the evening and come away with a greater understanding of this city that the Greeks founded in the 2nd century B.C. Split will be aglow as you follow the guide through the beautifully illuminated downtown, where you will see the palace that Roman emperor Diocletian built in the early 4th century. This complex of temples, cathedrals and residences is so spectacular that UNESCO declared it a World Heritage site. During the free time that follows the guided tour, you might pause for photos of other ancient landmarks such as the Golden Gate, the main entry that Diocletian passed through to reach his palace. For a glimpse into Split’s contemporary lifestyle, walk along the Riva, the bustling promenade that runs along the sea. It is a hub for shopping and dining and looks especially attractive at night with the city lights reflecting off the water.
