For historians, the History of Architecture is understood, roughly speaking, as the study of Architecture over time, broken down into narratives that, from a certain perspective and through successive stages, select, organize and sequence material and immaterial disciplinary facts. . They thus provide a vast source that allows an approach to the past of Architecture, fundamental and useful as knowledge in itself or as knowledge circumscribed in a particular focus.

However, for architects, the History of Architecture is far from being exhausted in the approach of historians, not only because their respective fields of activity and ways of seeing are distinct, but, above all, because the historical facts of Architecture offer an inexhaustible source for architectural thinking and doing, for the Design process. In this sense, from the outset, it can be said that the immensity of these facts are counterpointed by disciplinary constants beyond time, that is, they are more those than the underlying logics, matrices, models and architectural themes. And, therefore, even if each fact is unavoidable in its own time, it is possible to summon it outside of this, either by recognizing specific situations in it, or by equating such situations with identical situations from different times, or even by transporting them to other contemporary or future situations. .

It would be said that for each Project circumstance – territorial, spatial, formal, expressive, programmatic, material – there are similar ones in the past, a powerful resource for the project process. And this also means that identical architectural guidelines for critical judgment are possible for any architectural fact at any time. Perhaps for architects, more than the History of Architecture, they are more interested in the Architectures of History. As well as the inspiring possibility of an Imaginary Museum for design activity.
