Lisbon has inspired explorers for centuries with its stunning setting at the Tagus River’s mouth. Its labyrinthine streets carry echoes of 16th-century navigators who sailed on the winds of the Age of Discovery. The city prospered greatly from its trade. And today’s streets are lined with the legacies of wealthy builders, including the Jerónimos Monastery and Belém Tower, stunning works that introduced Manueline architecture. Savoring local cuisine and port wine are favorite pastimes here. On any evening, the strains of fado spill from clubs in the historic Alfama District.
