This article draws on the postcolonial legal theories and the concept of imaginative geographies, aiming to shed light on the process of producing and realizing Israeli representations of the Negev Desert through the implementation of legal regulations. The focus is on chosen imaginations of the Negev Desert, researched here as a case study of material realisation of imaginative geographies. In the analysis, symbolic narratives, visions of spaces, and new categories, intertwined in legal acts as their foundations, justifications and goals are underlined. The conclusions of presented study show that imaginations and visions can be in fact reproduced in space through legal regulations, and in the analysed case law has three aspects: it is an expression of imagined geographies; it translates those visions into technical terms; and lastly, the implementation of its provisions becomes the main instrument of producing those representations in reality.
