In the Finnish city of Jyväskylä, is the old factory of Kangas. The trace left by the history of this place is evident. The space of the city is not a neutral space. A building is not equivalent to another and its presence in the urban space profoundly modifies the relations between the parts of the city and, above all, changes the relationships between people. A challenge in the architecture of today and the future, could be to think of public spaces as spaces of consensus: an urban space in which it is possible to recognize the identity of the whole world through built heritage: this is the element basic development of a society capable of identifying itself in its own stones. This new architecture must give the city more than it receives from it, just as monuments have done through the centuries. In this sense, the heritage can represent an ideal guide so that the development of the constructed thing and that the development of the society generates a constant and proactive dialogue
