Joint Base Myer–Henderson Hall

Joint Base Myer-Henderson Hall is a military installation in the National Capital Region that combines Fort Myer, Fort McNair, and Henderson Hall into one connected facility. The base provides administrative services, family support programs, and operational headquarters for active-duty personnel stationed in the area.

The installation was formed by merging three historic military sites: Fort Myer established in 1863, Fort McNair dating to 1791, and Henderson Hall which opened in 1941. These separate facilities were consolidated into one base to streamline military operations and administration.

The Third United States Infantry Regiment and Army Band 'Pershing's Own' perform military ceremonies and maintain traditions at Arlington National Cemetery.

Access to the base is restricted and requires proper authorization and a valid identification for visitors. Those planning to visit should contact ahead to understand current access requirements and any visitor procedures.

Grant Hall at Fort McNair contains a courtroom where the military tribunal following President Lincoln's assassination convened in 1865. This space preserves a critical moment in American history within the grounds of the modern installation.
