Lisbon is the capital and the largest city of Portugal, with an estimated population of 552,700 (2011). About 3 million people live in the Lisbon Metropolitan Area (which represents approximately 27% of the country's population).
From imposing São Jorge Castle, the view encompasses the old city’s pastel-colored buildings, Tagus Estuary and Ponte 25 de Abril suspension bridge. Nearby, the National Azulejo Museum displays 5 centuries of decorative ceramic tiles. Just outside Lisbon is a string of Atlantic beaches, from Cascais to Estoril.
Lisbon's economy is based primarily on the tertiary sector. Most of the headquarters of multinationals operating in Portugal are concentrated in the Grande Lisboa Subregion, especially in the Oeiras municipality. The Lisbon Metropolitan Area is heavily industrialized, especially the south bank of the Tagus river (Rio Tejo).
The country's chief seaport, featuring one of the largest and most sophisticated regional markets on the Iberian Peninsula, Lisbon and its heavily populated surroundings are also developing as an important financial centre and a dynamic technological hub. Automobile manufacturers have erected factories in the suburbs, for example, AutoEuropa.
