The National Building Museum aims to advance the quality of the built environment by educating people about its impact on their lives. As the leading American cultural institution devoted to the history and impact of the built environment, the National Building Museum tells the stories of architecture, engineering and design. As one of the most family-friendly, awe-inspiring spots in Washington, D.C., visitors are welcomed from around the world to exhibitions, public programs and festivals. Located just four blocks from the National Mall, the Museum occupies a magnificent building with a soaring Great Hall, colossal 75-foot-tall Corinthian columns and a 1,200-foot terra cotta frieze. Since 1985, the Museum has presented more than 200 exhibitions to critical acclaim, and features adult, youth and family programming.
