Lisbon nestles against seven hills on the north side of the Rio Tejo (Tagus River). Many of the city's attractions are within walking distance of eachother in the central city area. Charming, medieval Alfama with its maze-like streets sits to the east, crowned by the magnificent Castelo de São Jorge. The Baixa's grid of tidy commercial avenues lies next to it, stretching from the riverfront Praça do Comércio up to the Praça da Figueira.
The elegant Chiado shopping area climbs away to the west, while at the top end of the Baixa, the Elevador de Santa Justa sits at the juncture of the Bairro Alto. A traditional residential area, the Bairro Alto (high quarter) is also home to much of Lisbon's nightlife.
