Geometry of Light is an immersive intervention at the Barcelona Pavilion envisioned as a contemporary lens for this important masterpiece, highlighting and expanding upon the architectural and material features of this structure. Using the 1929 Pavilion, designed by Ludwig Mies van der Rohe and Lilly Reich, as the foundation of the work, Geometry of Light creates a new interpretive layer extending from the primary elements of the architecture, including the gridded plan, vertical planes, and materiality.
