Lisbon can be summed up in one word: variety. From the 12th-century Se cathedral to the modern bridges spanning the Tagus River, from the 18th-century Aguas Livres aqueduct to the futuristic Oriental Station, Lisbon traverses the ages. The city's many neighborhoods include Moorish Alfama, home of the city's tallest hill, and 17th-century Bairro Alto, with its hopping nightlife. Museums, castles, open-air markets, funiculars, Fado music - Lisbon's pleasures include these and much more.
