The National Building Museum was signed into existence on December 12, 1980. To celebrate our four decades, we're creating a video overview of our past and our future, along with memories and well-wishes from members of our community. Enjoy the video, now published on our website.

On the occasion of our 40th Anniversary, we would like to recognize our generous supporters.
