Architectures of Security: Design, Control, Mobility examines the relationship between architecture, security, and technology, focusing on the way these factors mutually constitute a “ferocious” architecture—an architecture, aesthetic, or design that is violent, forcing the performances and practices of sovereign power and neoliberalism. The text provides examples from urban spaces in both the global north and south, which discipline the mobility and movement of populations, as well as reinforce socioeconomic cleavages. From borders and borderlands, to airports, museums, and public buildings, the authors portray often inhumane examples of sovereign power.
