Lisbon
The capital city of Portugal makes for a great destination on any Atlantic cruise of Europe or Douro River cruise, with iconic sites like Jerónimos Monastery (Late Gothic Manueline architecture), the four-story limestone Belem Tower, the Castle of São Jorge, and others. Just outside of Lisbon you will find sites like Serra de Sintra, where the Portuguese royal family once lived.
