A collection of texts, projects and images by the Parisian architecture studio on the subject of the highway, the most radical public space ever imagined, but also the most divisive and criticized today, questioning our relationship with modernity. The highway as an obsession, capable of illuminating the unconscious of an architectural practice. Such could be the succinct description of this book, that gathers unreleased or already published texts by Studio Muoto on this intriguing theme. This eclectic collection of texts – extracts from articles or lectures, notes, project descriptions – is complemented by an outright photographic scrapbook produced by the architects who designed the French pavilion at the 18th Venice Architecture Biennale, 2023. These images, taken during their travels and their many projects, illustrate their obsessions as much as the wanderings of their thoughts. Holy Highway reflects the principle of the exploratory journey as the foundation of an architectural sensibility.
