How Heavy is a City? Exploring the Lisbon Architecture Triennale 2025

Subscriber Access

How heavy is a city, and what does that weight mean for our collective future? This provocative question guides the 7th edition of the Lisbon Architecture Triennale, which proposes an inquiry into the transformations of urban life and the material, social, and environmental consequences of inhabiting the planet today. From October 2 to December 8, Lisbon will once again host one of Europe's most significant architectural events.

Curated by Ann-Sofi Rönnskog and John Palmesino, founders of the practice Territorial Agency, the Triennale investigates the magnitude of contemporary cities and their planetary impact. Composed of nearly 30 trillion tons of materials, global cities form a dense and intricate web of continuously evolving structures. To unpack these complexities, the Triennale opens itself as a space of learning, curiosity, imagination, and debate — a meeting ground for architects, researchers, artists, and the wider public.
