Lisbon concentrates on a limited territory many tourism sectors; but for mountains and snow, of lesser importance in Portugal, the metropolitan area has heritage, culture, beaches, events, conventions and nearly any sort of tourism activity in several organizational and economic segments; it is a situation not unlike that of Barcelona.
Lisbon is also the third most populated metropolitan area in the Iberian peninsula after Madrid and Barcelona, and can be proud of one of the most monumental and interesting old cities of Europe.
The fact of having been the capital of a world empire, liquidated by the carnation revolution in 1975, and the traces of that old splendor as seen in a context in which unfortunately decadence is in some areas beyond poetics, marks the city. Old trams have survived in a large measure due to the fact that the city lacked some modernizing waves that were present in other parts of Europe, to become today a tourism asset, and a sustainable mobility one too. The persistence of the traditional paving on sidewalks is in part the result of the resilience of a costs structure in the public works that no longer exists in other areas. On the other side, the 25 de abril bridge as seen from the Praça do Comercio configures an interesting metropolitan landscape.
The Plano Estratégico do Turismo de Lisboa 2007-2010 develops the aims of the national strategy, and has a goal to increase value through modernity, authenticity and experience. The plan proposes three micro-centralities along the Tagus shore: Belem, the historical center and the Parque das Naçoes, where Expo 1998 was held.
