One of Slovakia's most impressive castles sprawls across a cliff above Trenčín. The town is far older than its most famous fortification: Roman legionnaires stationed in Trenčín (then Laugaricio) in the 2nd century AD even left a cliffside inscription as a memento. The town's other claim to fame is Slovakia's largest music festival, a genre-straddling epic hosted in Trenčín each summer.
After hiking up to the castle and drinking in the views from its ramparts, dawdle among the comparatively youthful 18th- and 19th-century buildings of Trenčín's town centre. Two interlocking pedestrian squares are lined with pubs and restaurants to while away the hours after sundown.
