Theatrum Mundi is a network of people from the performing and visual arts, the built environment disciplines, from across the academy and community and social collectives. Based in London, with partnerships in New York, Paris and Beijing, it activates projects, meetings, and research in cities around the world. Theatrum Mundi asks questions about urban culture. Who makes it? Where does it take place? What are the politics of production and display? What are the connections between performance, design and politics, and how can those connections help us understand cities?
