Novi Sad, Serbia’s second-largest city, sits along the banks of the Danube River and has long served as a cultural meeting point in the Balkans. Its centerpiece is Petrovaradin Fortress, a massive 18th-century stronghold nicknamed the "Gibraltar on the Danube." The fortress is known not just for its historic architecture but also for its network of underground tunnels and the iconic clock tower where the hands are reversed, meaning the large hand shows the hour.

Spello sits high on the slopes of Mount Subasio in the heart of Umbria, where visitors step into a place shaped by centuries of history. Each year, Spello’s streets become a living canvas during the Infiorate di Spello, a long-standing celebration tied to Corpus Christi. Residents work through the night before the feast to lay flower petals along the town’s main thoroughfares, creating patterns and images that stretch for over a mile.

Ronda, perched high above the El Tajo gorge in southern Spain’s Málaga province, offers one of the most dramatic landscapes in Andalusia. The city is split in two by a 120-meter-deep canyon carved by the Guadalevín River, and connected by the iconic Puente Nuevo, an 18th-century stone bridge that took over 40 years to complete. Visitors crossing the bridge can stop at the viewpoint built into the stone itself, once used as a prison.
