Lisbon, the capital of Portugal, is one of Europe's most beautiful and cosmopolitan cities. Set over a series of hills near the mouth of the River Tagus, it's a place inextricably linked with the sea. Intrepid navigators embarked from here in the 15th and 16th centuries to sail unknown waters and chart new lands, and the legacy of this golden Age of Discovery underpins much of the city's culture and heritage.

Lisbon is a colorful and vibrant destination. Renowned for its warm and sunny disposition, the city is blessed with a wealth of historic monuments, world-class museums, and a host of other fabulous things to do that can easily be worked into a single or multi-day itinerary. You can explore the narrow streets of the old quarter, stroll the riverbank promenade, or wander through verdant parks and gardens. In fact, enjoy Lisbon like the locals do, at an easy and unhurried pace, and you'll quickly fall for its welcoming character and beguiling charm.
