Building 40, Georgian revival building at Walter Reed Army Medical Center, Washington, D.C., United States.
Building 40 is a three-story structure with brick exterior walls and limestone trim at its entrances, including a raised stone basement at the Walter Reed Army Medical Center. The facility is divided into four distinct wings positioned at the intersection of 14th and Dahlia Streets.
The structure was completed between 1922 and 1932 and initially served as home to the Army Medical School. It later became the Walter Reed Army Institute of Research and remained a medical research hub until 1999.
The pavilion names honor medical pioneers who shaped military medicine, serving as reminders of their research contributions that remain part of the building's identity. These designations reflect how the place maintains a tangible connection to figures who influenced its scientific purpose.
The building is accessible on foot at the Walter Reed Army Medical Center and sits at a clear intersection for easy navigation. Be aware that as a military facility, access policies apply and visitors may need prior authorization.
The basement housed one of the first nuclear reactors installed in the United States, making it a notable piece of scientific heritage. This technical milestone demonstrates the advanced research work that took place within these walls.
