The picturesque little town of Amalfi was once a major Mediterranean naval power, but a devastating earthquake in 1343 cut the city down in its prime and destroyed most of its historic buildings.

The lovely town of Sorrento, draped across rugged cliffs overlooking the Bay of Naples, has been charming visitors since the days of the Grand Tour. The Renaissance palaces and many craft shops make Sorrento an attractive destination in its own right, and it’s also a jumping off point for Capri, Pompeii and the Amalfi Coast.

The down-to-earth port of Sète, sandwiched between the Mediterranean and the Etang de Thau lagoon, is a working town rather than a tourist hotspot, though the canals and colourful buildings have a certain charm.

Sovereignty of ‘The Rock’ has been a thorny issue ever since Gibraltar was ceded to Britain in 1713, though on the ground it’s clear where most locals’ sympathies lie.

Seville is a wonderful destination, a sophisticated and sun-kissed city on the banks of the Guadalquivir river.

An important naval base and major commercial port, Cherbourg is the gateway to the many attractions of Normandy, including the Bayeux Tapestry and the beaches where the D-Day landings took place. Cherbourg’s excellent Cité de la Mer maritime museum is also well worth a visit.

Rouen has endured a turbulent history: it was here that Joan of Arc was burnt at the stake in 1431, and much of the city was destroyed during World War II.
