Besźel is a fictional city featured in the novels of author China Miéville, particularly in "The City & The City." It is characterized by its unique geographical and cultural landscape, where two cities coexist in the same physical space but are perceived as separate entities by their inhabitants. The residents of Besźel must adhere to strict social rules to avoid "breaching," which is the act of acknowledging the existence of the neighboring city, Ul Qoma. This separation creates a complex dynamic, influencing the daily lives of its citizens and the narrative of the stories set in this intriguing urban environment.
