Abstract
If we want to give flesh and blood to the history of places of power, and not just map their symbolic relationships in the abstract, we need to focus on describing, in situ, the behaviors they architect. First and foremost, the behavior of the princes : Cola di Rienzo in Rome, like Filippo Maria Visconti in Milan, adopted attitudes, gestures and ways of living that made the accusation of tyranny credible. In this way, the façade of a palace can be seen as the authoritarian or threatening face of a political enemy. This engages a dynamic of qualification, dequalification and requalification of spaces - and it's by following the uncertain future of the term forum from Renaissance Italy to Napoleon's regeneration of its prestigious structures that we gain a better grasp of the way in which the social construction of their architectural efficacy is constructed through the naming of places. For example, from the XVthcentury onwards, certain fortresses could be seen as bastilles. In this case, as in the case of the Bastille in Paris on July 14 1789, it is their dismantling that establishes them as places of memory.
