Gaebler Children's Center was a psychiatric institution operated by the Massachusetts Department of Mental Health for severely mentally ill children and adolescents, located in Waltham, Massachusetts. The center opened on October 8, 1955, near the grounds of the Metropolitan State Hospital and closed in September 1992. It was named after William C. Gaebler, the second superintendent of the Metropolitan State Hospital. The Massachusetts Department of Mental Health (DMH) closed the center as it was antiquated and could no longer serve the needs of the children it housed. According to the DMH, this closure coincided with the decision to place mentally ill children in community settings instead of in institutional settings. Others felt the center was closed due to budget cuts. According to the Waltham Land Trust and The Boston Globe, the grounds of the Gaebler Center are currently being considered for redevelopment. (The Gaebler Center is now slated for Demolition with bids to be received prior to April 15, 2010)Demolition and site development contractor Testa Corp won the bid to begin destruction of the area, as indicated by a sign recently erected at the entrance. Mayor Jeanette McCarthy said the building was bought by the city of Waltham in 2005 in order to have some control over the development of the seven-acre site. Demolition of the Gaebler Children's Center was completed in January 2011. The work cost the City of Waltham approximately $637,000. There are no current plans for the 55-acre lot.

The Murphy Army Hospital is a former hospital in Waltham, Massachusetts. The hospital grounds, now demolished, is now home to Gann Academy, Bentley University Residence Halls, and City of Waltham Veterans Memorial Park- which contains sport facilities. During its operation, it was also home to a sports team called the Murphy Medics. From June 1, 1949, to April 30, 1950, the hospital was the site of an experiment, ordered by the Surgeon General of the United States Army, Major General Raymond W. Bliss, to determine "to what extent women could be substituted for men in the operation of Army hospitals". During the 11-month period, 240 civilian women and members of the Women's Army Corps replaced men in the majority of medical and administrative jobs. However, no women Army doctors were available and "costs precluded the hospital's hiring of civilian women for the experiment." There are several remains of Murphy Hospital still surviving. The main driveway to the Hospital off Trapelo road remains with original brown wood sign holders as well as a lamp post at the end of the roadway. One building from Murphy Hospital remains. The original hospital maintenance shop is still standing on property behind Gann Academy.
