Protest movements shape public space not only through their messages, but in many cases also through their—mostly temporary—buildings. Protest Architecture: Barricades, Camps, Spatial Tactics 1830–2023 is the first-ever international survey of the architecture of protest, presented it in all its manifold forms and, in some cases, ambivalence.
