The existing Fort Sam Houston Museum was built in 1905 and takes visitors through the history of the Army in San Antonio from establishment of the post in 1845 to present day JBSA-Fort Sam Houston.
Much like other areas of the rapidly-growing military presence in San Antonio, the museum has outgrown its space, and the building was old and deemed not up to standards. The U.S. Army Center of Military History said to shut it down, but Army North invited the museum to relocate to the historic Quadrangle.
