The late Renaissance St Peter's Basilica is an iconic landmark of the Vatican City, a monumental structure that the likes of Michelangelo helped bring into existence. Today, the basilica is open to visitors wishing to explore its inside naves and chapels and see works of art by great masters such as Raphael and Bernini. While here, don't miss out on climbing to the top of the dome, where the stunning view of St Peter's Square awaits you.

Located in the heart of Bremen, the Glocke concert hall has been enthralling audiences since 1928. The unique acoustics of this building have impressed a multitude of famous classical musicians. Every year, the Glocke hosts more than 200 events, including classical music recitals, theatrical performances and jazz concerts.

Siena still runs on medieval time—in the best way. Its centre hasn’t changed much in centuries, and that’s part of the charm. The Piazza del Campo is the heart of it all—it’s where the Palio horse race happens twice a year. Climb the Torre del Mangia for wide views across the rooftops. The cathedral’s worth the time, especially its black-and-white striped interior, detailed floor mosaics (open seasonally), and the Piccolomini Library tucked inside. Don’t skip the crypt or the Museo dell’Opera del Duomo—they’re quieter and give you a different angle on the city.
