Cruises departing from Leixoes, Portugal

Porto, Portugal's second largest city after Lisbon, is one of Europe's oldest cities and was registered as a World Heritage Site by UNESCO in 1996. Of course, Porto's name itself hints at perhaps Portugal's most famous export—port—for it is here that the fortified wine was first produced. The city is reminiscent of times gone by and you wouldn’t be far wrong to liken it to an ideal Shakespearean backdrop. Here, the skyline is composed of sky-high bell towers, opulent baroque churches and majestic beaux art buildings, which combine to create a romantic air that’s only heightened by the glorious shafts of sunlight that illuminate the city.
