Lisbon (in Portuguese, Lisboa; pron. IPA /liÊ’.'βo.É?/) is the capital and largest city of Portugal. It is the seat of the district of Lisbon and capital of Lisboa e Vale do Tejo region. Lisbon has a population of 564,657 and its metropolitan area has a population of 2,665,000.
Lisbon is situated at 38°43' north, 9°8' west, making it the westernmost capital in mainland Europe. It is located in the west of the country, on the Atlantic Ocean coast at the point where the river Tagus flows into the Atlantic Ocean. The city occupies an area of 84.6 km². It is important to say that, unlike most major cities, the city boundaries are narrowly defined around the historical city perimeter. This gave rise to the existence of several administratively defined cities around Lisbon, such as Loures, Odivelas, Amadora and Oeiras, which in fact are part of the metropolitan perimeter of Lisbon.
The historic centre of Lisbon is built on seven hills, making some of the city's streets too steep for motor vehicles; the city is served by three funicular services and one elevator. The western side of the city is mainly occupied by the Monsanto Natural Park, one of the largest urban parks in Europe with an area close to 10 square kilometers (almost 4 square miles).
Lisbon is one of the warmest European capitals. Spring and Summer months are usually sunny and maximum temperatures close to or above 30 °C during July and August, with low between 15 and 20 °C. Autumn and Winter are typically rainy and windy, yet sunny days are not rare either, the temperatures rarely fall below 5 °C, usually staying at an average of 10 °C. Average sunny hours per year are 3300 h/y, and 100 days with rain per year. Lisbon climate is strongly influenced by the Gulf Stream.
The population of the city is 564 657, and the metropolitan area (Greater Lisbon) is 2 665 000. Lisbon is located in the wider region known as Lisboa e Vale do Tejo, with a population of 3 500 000, constituting about a third of the population of Portugal. The population density of the city itself is 6 606.9 inhabitants per km2. It's expected that the population of the Lisbon Metropolitan Area will increase to some 4,5 million by 2015 and more than 5 million by 2020. It's the fastest increasing region in Portugal.
The heart of the city is the Baixa or downtown; this area of the city is being considered for UNESCO World Heritage Site status. The Baixa is organized in a grid-system and a network of squares built after the 1755 Lisbon earthquake, which leveled a big part of the medieval town. The Castle of São Jorge and the Santa Maria Maior Cathedral are located on one of the seven hills of Lisbon, to the east of the Baixa. The oldest district of the city is Alfama, close to the Tagus, which has made it relatively unscathed through the various earthquakes. Other monuments include:
The Castle of São Jorge, atop the tallest hill of the central city, Praça do Comércio (Commerce Square), Rossio Square, Restauradores Square, Elevador de Santa Justa, an elevator (lift) in Gothic revival style, built around 1900 to connect the Baixa and Bairro Alto. Jerónimos Monastery, Belém Tower The city of Lisbon is rich in architecture; Romanesque, Gothic, Manueline, Baroque, Traditional Portuguese, Modern and Post-Modern constructions can be found all over the city. The city is also crossed by great boulevards and monuments along these main thoroughfares, particularly in the upper districts; notable among these are the Avenida da Liberdade, Avenida Fontes Pereira de Mello, Avenida Almirante Reis and Avenida da República.
