The subject of this article starts from studies that come being developed regarding the use of Mnemonic structures in relation to the conception of spaces, architectural projects, and its correlations with the images languages and the signs and its occurrences, applications and uses in spacial uses. Great part of the current examples of memorization structures applications in spacialities design are related to experimental virtual environments, mainly tied with the artistic production and/or the studies of design of user-computer interfaces. Our research suggests a new look at this subject, considering to investigate, beyond the virtual spacialities, applications in the concrete and hybrid spaces. In this article we propose to argue the subject from two metaphors related to the theater: the metaphor proposal for Brenda Laurel in Computer as a Theatre and the boarding of Giulio Camilo [ 1480-1544 ] in its Theater of the Memory.
