Lisbon, the westernmost European capital city, lies with the Sintra Mountains to the north and the Tagus River to the south. This old city with a long and storied history is built atop seven hills, its topography undulating between high and low. Buildings are constructed like mountain ranges, with old churches and monuments found throughout its dense medieval atmosphere. The new city district is a veritable forest of modern buildings. Even though the World Exposition Park is far away, it is still a good destination for for a leisurely walk. There is also the area of Belém replete with a nautical atmosphere, where you can walk and admire the exquisite architecture in the the glow of the setting sun. A sunset like this is absolutely unforgettable!
