How Heavy is a City?
This question instigates a three-year research project into the complex set of transformations of both the city and its backdrop, revealing a new figure in the making with a magnitude of planetary dimensions. To make sense of these transformations and sort out the underlying agencies, a re-assembly of architecture and what it means to build a collective environment is required. 

The next edition of the Triennale aims to open a public space of learning, experience, curiosity, inquiry, debate, delight, outrage, speculation, transgression, imagination and action about the possible futures of cohabitation. How Heavy is a City? explores emerging forms of cooperation and mutuality, establishing a new unit to evaluate architecture to recast its role as a driver of debate.

Ann-Sofi Rönnskog and John Palmesino, founders of Territorial Agency, are the Chief Curators, leading an investigation of the spatial dimensions of the transformations marking the Anthropocene by asking questions of design, governance, agency and proposition. Opening in the Autumn, the Triennale 2025 acts as a convener, engaging a broad team of experts from science to philosophy or the arts ​​who participate from the outset in a programme branched off into three lines of research – Fluxes, Spectres, and Lighter – each one resulting in an exhibition, book chapter and talk series.
