Muir College unfolds as a Brutalist maze amongst towering trees
Muir College at UC San Diego, founded in 1967 and named after naturalist John Muir, exemplifies brutalist architecture within a unique natural setting. The campus, initially envisioned by architects Robert Alexander and A. Quincy Jones, was further developed by executive architect Robert Mosher, who drew inspiration from Yosemite National Park to create a distinctive design where concrete structures integrate with the surrounding landscape.
Key buildings such as Tioga and Tenaya Halls showcase the bold forms typical of brutalism, characterized by their raw concrete surfaces and geometric shapes. The campus is a seamless interplay between architecture and nature, where dense concrete volumes contrast with the verticality of trees, creating a dynamic relationship between built and natural environments.

the design blends monumental brutalist qualities with nature
The design merges the monumental qualities of brutalist architecture with a sense of immersion in nature, positioning Muir College as a notable example of brutalist architecture. The interaction between sunlight and the warm tones of the concrete further enhances the visual experience, adding depth and warmth to the stark materials. Muir College remains a significant architectural landmark that continues to reflect the broader aesthetic and environmental considerations of its time. The project was recently captured by architectural photographer Marco Petrini.
