It’s often said about architecture that it can nei- ther be critical nor against something because all building is literally a constructive process. Building is said to occupy a place within social circumstances, whether dependent on money or clients, and therefore cannot question anything per se. However, exceptions can be found.

From Gottfried Semper’s barricades and his forced migration to Vienna, from the camps of the anti-nuclear power plant movement and those of the Occupy movement to the protests in Gezi Park and on Tahrir Square and the Maidan.
