For lovers of history and archaeology, there is a wealth of medieval and Roman ruins in the immediate surroundings of Split.

Set on a small island—a stepping stone between the mainland and the much larger Čiovo—is the ancient coastal city of Trogir. It's a small place, and it doesn't take longer than about five minutes to walk from any point in Trogir's historic center to reach the sea. Navigate the narrow stone streets, starting with the Garagnin-Fanfogna Palace, working your way to the Cathedral of St. Lawrence. Here, admire the Radovan's 13th-century Romanesque Portal and the bizarre creatures around the doorposts.

Next, stroll along the Riva, admiring the Romanesque, Renaissance, and baroque architecture and medieval fortress walls as you find your way to the 15th-century Kamerlengo Fortress. Ascend its ramparts for sweeping views over the island. And don't be surprised if you're serenaded by traditional acapella groups called klapa along the way.

As you return to Split, consider a short detour to visit the impressive medieval Klis Fortress. The more than 2000-year-old fortress is perched on top of an isolated rocky eminence. It overlooks Split and the ancient Roman settlement of Salona (now Solin)—the original capital of the Roman province of Dalmatae and one of the five largest cities in the entire Roman empire. Wander the large Roman amphitheater where early Christians were fed to lions—fit for a city of 60,000 at its peak. Salona is remarkably devoid of tourism, making it an unsung gem for those who want a more personal Roman experience.
