After the interruption of the 2019 edition due to the Social crisis in Chile, the Chilean Architecture Biennial returned to Santiago in January 2023 under the theme of 'Vulnerable Habitats', addressing issues such as "the emergence of the housing deficit in a context in which slums, informality, and illegal land takeovers have increased in recent years" and "the vulnerability and deterioration of public spaces; the urgent protection of tangible heritage; and environmental vulnerability in a context of a climate crisis."
