We hold a major forum every three years for the debate, discussion and dissemination of architecture that crosses geographic and disciplinary boundaries.

The first Triennale took place in 2007, under the theme Urban Voids. The chief curator, José Mateus, worked with a team of 23 national and international curators, that presented four exhibitions, an international conference, a lounge and five competitions.

In 2010, Let’s Talk About Houses, the second edition, consolidated the presence of the Triennale in culture events dedicated to architecture. Curated by Delfim Sardo, the program included four exhibitions, an international conference and four competitions.

With its third edition, Close, Closer, in 2013, the Triennale achieved solid international reach and recognition. The chief curator Beatrice Galilee and the curators José Esparza, Mariana Pestana and Liam Young programed exhibitions, conferences, talks and associated projects.

Envisioned by curators André Tavares and Diogo Seixas Lopes, the fourth edition of the Triennale, The Form of Form, in 2016, included four exhibitions, a series of talks, seven Satellites, three awards, two conferences, 12 associated projects, four publications and a group of Sidekicks.

In 2019, between 3 October and 2 December, The Poetics of Reason received over 92,000 visitors. The curatorial team led by Éric Lapierre, was chosen through an open call and was also composed by Sébastien Marot, the duos Mariabruna Fabrizi and Fosco Lucarelli, Ambra Fabi and Giovanni Piovene and Laurent Esmilaire and Tristan Chadney. Five central exhibitions, ten associated projects, conferences and three awards were the basis of this fifth edition that did everything to unveil reason in architecture to the general public.
