Architect Moshe Safdie describes the Crystal Bridges project, which is both a museum and a cultural center. The project is located in a ravine with a creek fed by Crystal Springs. Two suspended-cable-and-wood buildings span the ravine, creating two ponds. These structures serve as dams as well as bridges. The design aims to protect the natural beauty of the site while emphasizing a strong sense of place, and certain materials – wood, fieldstone and limestone aggregate – are drawn from the region. Building walls are architectural concrete with wood inlays, and the roofs are composed of a system of laminated wood beams. The liberal use of glass throughout the complex provides great transparency and enhances views of the site.
