The main topic of the paper is the reconstruction and revitalization of the Old Belgrade Fairground, a significant part of Belgrade's cultural and historical heritage. The research methodology involved identifying spatial phenomena at the Fairground site. By applying these phenomena as space generators, a new architectural language, rooted in the history and architecture of the location, is introduced. Through the lens of the primary phenomenon of the "depth of memory" and the secondary phenomenon of "the shell" the Old Belgrade Fairground becomes the embodiment of an spatialized narrative, focused perception, and distanced empathy. Interspersed with focal points and public corridors, Sajmište emerges as a layered architectural-urban complex, with its primary function being the spatial manifestation of memory.
