Poly Pavilion
Also known as The Structure.
No. 19 · 1985
The structure is an architectural and engineering triumph that has captivated visitors since its completion in 1985. Its design, inspired by Heinz Isler’s pioneering work with catenary curves, explores the mathematical beauty of tension and compression. Inverting the natural curve of a hanging chain to create three sweeping arches, the pavilion achieves a harmonious balance of structural efficiency and visual elegance.
Constructed using precast concrete, the pavilion spans 40 feet and stands 8 feet at its apex, with a radial layout that emphasizes symmetry and flow. The students’ choice of precast elements allowed for efficient formwork and on-site assembly with crane assistance—an impressive logistical feat for a fully student-led project. The pavilion’s compression arch design maximizes material efficiency while minimizing maintenance, ensuring its longevity in the elements.
Today, the structure has earned a reputation as one of the most popular destinations in the canyon. Its open, web-like geometry invites visitors to interact with it in creative ways—whether by hammocking between its beams, gathering beneath its arches, or stargazing on clear nights. Despite its minimalist appearance, the pavilion’s intricate geometry creates a space that feels both expansive and intimate, drawing visitors into its unique interplay of light, shadow, and structure.
The Poly Pavilion endures not only as a piece of experimental architecture but as a beloved landmark, connecting generations of students and visitors through its timeless design.
