Sometime around 300 A.D., Roman Emperor Diocletian built his retirement palace on one of the loveliest spots on the Adriatic Sea. Today his palace has become a UNESCO World Heritage Site in the heart of Split, the city that grew up around it. Split is now Croatia‘s second largest city, and much of it sits on a beautiful peninsula on the island of Ciovo, a jewel on the Dalmatian Coast. Many intriguing relics from the Roman, Greek colonial and Medieval periods can be found in Split‘s archaeological museum, which was founded in 1820, making it Croatia‘s oldest museum. One of the top outdoor attractions is the green oasis of Marjan Forest Park with its Split Zoo. There are also plenty of fine beaches nearby.
