The article aims to bring into discussion architecture as cultural ingredient, and to investigate the current status of the consecrated or of the recently established heritage (patrimony) as well as to ask questions about the contribution that the experiments of professionals may have in the space of the city. If the architecture educates, innovates, launches questions and controversies, it continuously complements the in situ image of the place, city, or, at global level, of the conceptual, technological and innovative developments. Whether it addresses the town-dweller, the user, the tourist or the curious, architecture continually writes new expressions in city space, negotiating with tradition, arguing and reconstructing fragments of urban life. How much is it accepted, pleasant / loved or challenged - or how much it pleases the initial or subsequent demands, are sensitive discussions in the dedicated domain. Regarded at the level of the object or the ensemble, architecture can be a scenographic background for the city or a piece in the set, a point on a route - landmark of urban paths, or simply an unfolded surface which accommodates activities. From level of the area of discussion, architecture is also another space, the one of debates - from the principles in line with the problems of the world for which it strives to find an answer to the philosophical, the local and the ones related to the built application.
