FORT MCNAIR, Washington, D.C. -- Joint Base Myer-Henderson Hall announces its quarterly Public Open Houses of Grant Hall's historic third-floor courtroom, located on the Fort McNair side of the Joint Base in southwest Washington D.C., from 10 a.m. to 4 p.m. on the first Saturday of the second month of each quarter. The courtroom is the site of the military tribunal, held from May through June 1865, of those thought responsible for the plot to assassinate President Abraham Lincoln.

During a calendar year, the months of the scheduled open houses are February, May, August and November. The next Grant Hall Public Open Houses are Aug. 6 and Nov. 5 in 2016 and Feb. 4 and May 6 in 2017. Open House hours are 10 a.m. to 4 p.m.

During a 2009-2012 renovation of Grant Hall, which was originally part of Washington's Federal Penitentiary from 1829 to 1868, the third floor of the building was restored to depict the courtroom as it appeared during the 1865 trial. Courtroom features were recreated based on artistic renderings and written descriptions of court proceedings. Some furnishings and artifacts on display are on loan from the production company of a 2011 historical film about the trial, and other artifacts and documentation are from the National Defense University Library.

Members of the public are invited to the Public Open House, which is free to attend. Guests without a Department of Defense (DoD), Federal or AIE (Automated Installation Entry) ID are required to register to attend.
