In this city, you can build multiple tours. Choosing the theme of urban redevelopment, there are two very rich insurmountable experiences as a process of urban management and as architecture as a process: the Park of Nations and Chiado.
The first is located at the edge of the river above a run-down area which is occupied by industrial units in the process of becoming obsolete. Lisbon's 1998 World Exhibition was a chance to build a new city, a move unprecedented since the end of the Estado Novo (the totalitarian government 1919-1974). At this site we have the opportunity to visit some significant architectural objects by such names as Siza Vieira, Carrilho da Graça, Manuel and Francisco Aires Mateus, Manuel Salgado, Manuel Tainha and Peter Chermaief, and some of the best outdoor architectural examples by the landscape architects João Nunes and João Gomes da Silva.
The other site we will visit, the Chiado, is at the heart of the city. Following the great fire of 1988, Siza Vieira has intervened in this 'grand edifice', which constituted Lisbon in the era of Marques of Pombal. Vieira has reconstructed the 18th Century Chiado, giving us a masterful lesson in intervention in heritage.
