Visit Catania

The world's largest car-free old city.

The largest covered bazaar in the world, a Blue Mosque and the carpet-weaving capital of Persia.

A city built on water with no cars — gondolas, Byzantine mosaics, and getting happily lost in the back canals

The Renaissance in one walkable city: Michelangelo's David, Brunelleschi's dome, and the Uffizi

A walled medieval upper town above modern Bergamo — Venetian ramparts, funiculars and Lombard charm

A whole town of trulli — conical drystone houses found nowhere else, white and strange in the Puglian sun

The world's smallest state holds its biggest art: St Peter's, the Vatican Museums and the Sistine ceiling

Hike the smoking summit of Europe's most active volcano, 3,357 m above the Sicilian coast
