America 250: Time Capsule is a temporary museum pavilion designed by Foster + Partners for the United States’ 250th anniversary celebrations. The structure is planned for installation near the National Mall in Washington, D.C., where it will host exhibitions and public programming tied to the America 250 initiative. The pavilion is composed of interlocking geometric volumes with cantilevered elements that frame views of the surrounding civic landscape. Its exterior is wrapped in layered perforated metal panels that vary in density to regulate daylight and visibility into the interior exhibition spaces.
The pavilion is conceived as a lightweight, modular structure assembled using a steel frame system. Interior spaces are arranged to support exhibitions, circulation, and event use, with flexibility for changing displays. Building services, including lighting and climate control, are integrated within the structure to maintain clear interior volumes. The pavilion is intended to operate for the duration of the America 250 commemorative period.
