Glenn Dale Hospital
Glenn Dale Hospital was a tuberculosis sanatorium. It is a large facility, consisting of 23 buildings on 210 acre, that was built in 1934 and closed in 1982 due to asbestos. Though it will be eventually demolished, for decades it was an important public health institution near Washington, D.C. Park Police patrol the hospital grounds regularly.

The hospital was featured in an award-winning Washington Post Magazine article, "Quarantined," on Dec. 10, 2006, by Leah Y. Latimer, former staff writer and author. The article detailed Latimer's mother's hospitalization there in the 1950s and the emotional fall-out for their family from then to the present. Latimer gave a lecture on the grounds of Glenn Dale on October 4, 2008. It was the first time the public was allowed on the grounds in almost 30 years. The unadvertised event drew more than 150 people. Latimer said she plans more lectures around the area, based on her continuing research and 110+ interviews.

The hospital was listed on the National Register of Historic Places in 2011.
