There are several ways to conceive and perceive architecture, among many, however, it is believed that certain works denote silence, phenomenal manifestation that provides a certain empathic mobilization. Since architecture is an art that involves issues related to the material space in which man lives, the aim is to understand what makes a constructed work become essentially characterized by silence and what is necessary, in material terms, for this to happen. Therefore, this research is based on the concept of tectonics which, according to Frampton (1995, 1998), is one of the essential dimensions of architecture referring to constructive poetics. Thus, in addition to the discussion related to the concept of tectonics as a theoretical-methodological reference, the term silence, an idea intrinsic to the research, is mobilized, with the objective of analyzing certain architectural expressions that allow its emergence, synesthetically perceivable in architecture. Thus, three projects were selected for analysis: the Azuma House, the Bruder Klaus Chapel and the Brazilian Museum of Sculpture - MuBE; works where silence is in evidence, proving that, even though noise has always existed, it is possible to experience silence through architecture.
