Forest Glen Annex  The Forest Glen Annex is a U.S. Army installation in the Forest Glen neighborhood of Silver Spring, Maryland, USA. It is situated between Brookville Road and Linden Lane. Since 1999, the Annex has been the site of the Walter Reed Army Institute of Research (WRAIR) and the Naval Medical Research Center (NMRC), along with smaller units. In addition to the large research laboratories located in the Annex's "Daniel K. Inouye Building" (Building 503), the post includes a commissary, a child care center, and a Fisher House. There are also football and baseball fields, and picnicking facilities. In 2011, in accordance with the most recent Base Realignment and Closure (BRAC) recommendations, the Forest Glen Annex became home to the National Museum of Health and Medicine (NMHM) as well as a "Joint Center of Excellence in Infectious Disease Research." The former Army and Air Force Exchange Service (AAFES) post exchange was repurposed as office space and a new Navy Exchange (NEX) was opened at the nearby Walter Reed National Military Medical Center in Bethesda, Maryland. The Forest Glen property was acquired by the Army during the World War II era. Formerly known as the “Walter Reed Forest Glen Annex”, after many decades as a tenant of the Walter Reed Army Medical Center (WRAMC) in Washington, DC, authority over the facility was transferred on 1 October 2008 to the Installation Commander, Fort Detrick, Maryland. The Forest Glen Annex campus includes the National Park Seminary Historic District which is being redeveloped separately from the military area. The associated Glen Haven housing area in nearby Wheaton, also now owned by Fort Detrick, has 240 quarters for enlisted soldiers and for officers in grades O-1 through O-3. The land on which the Forest Glen Annex now stands was originally part of a huge tract belonging to the influential Carroll family of colonial times, which lived nearby. During the Civil War, the land was owned by Alfred Ray, a southern sympathizer. In July 1864, Ray allowed the troops of Confederate General Jubal Early to encamp on his land, before sallying down nearby Brookville Road for an unsuccessful raid on Washington, D.C., which ended in the Battle of Fort Stevens. Ray spent time in a federal prison for his action. During the period 1887 to 1894, the site was a short-lived hotel and casino, part of an ill-fated land development scheme.
