The town that gave the country (and port wine) its very name, Porto is Portugal’s second-largest metropolis after Lisbon.

The 14th-century São Francisco church is a main attraction, as are the local port wine cellars, mostly located across the river at Vila Nova de Gaia.

It’s been 200 years or so since he lived here, but Mozart is still very much Salzburg’s favourite son. Visit the composer’s residence and birthplace, then explore the Altstadt (Old City), taking in the baroque architecture.
