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.

This church is also known as the Church of the Holy Sepulchre and was built in 1130. The church is influenced by the round churches in Jerusalem. Back in the 15th century, the church featured a heavy gothic tower. However, in 1841, this caused a partial collapse in the round ambulatory. This is Cambridge's second oldest building.

Seville Cathedral is the third-largest cathedral in Europe. Originally built as a mosque in the 12th-century, the 100-metre- high minaret is now the Giralda clock tower. Christopher Columbus is buried inside the cathedral.
