This thesis focuses on the spectator's role in the performing arts and questions methods of deploying the foyer as an element of contemporary theaters. Current definition of the term foyer describes a statically defined architectural space, stiff prelude to the performance spaces itself. This practice of the foyer fails to recognize the importance of the social and experimental in attending the theater, losing the opportunity to prepare and stimulate the spectator for the erformance itself. The interaction of intellectual and spatial realms of theater and to what degrees the public determines this interplay are critical factors in this inquiry. The theater is not limited to the course of events within itself; it esonates outside of its physical boundaries. In this way the pathway of the spectator interwines with the experience of the city. This path to the Performing Arts is a Process, a passage through a sequence of spaces carrying the spectator to another level of perception in order to absorb the performance and to reflect on their lives. This process is defined as "Die Schleuse zur Darstellenden Kunst".
