Jefferson Barracks Military Post - Post-World War II

Post-World War II

After Jefferson Barracks was decommissioned, portions of the grounds were sold off for construction of houses. Some of the barracks were acquired by the St. Louis County Housing Authority as temporary low-cost housing. Those were demolished in the 1960s and replaced by the current Jefferson Townhomes development. Bishop DuBourg High School was located on the Jefferson Barracks property for several years in the early 1950s. The former Jefferson Barracks School is now used for storage and maintenance; and the former theater is St. Bernadette Catholic Church. It is now the site of two St. Louis County Parks (Jefferson Barracks County Park and Sylvan Springs County Park), a National Guard Base (Army and Air), the Jefferson Barracks National Cemetery and a Veterans Administration hospital. Part of the hospital grounds were donated to the Mehlville School District in the 1960s to build Charles S. Beasley Elementary School.

Jefferson Barracks County Park includes several museums that house artifacts and history of Jefferson Barracks while it was an active United States Military Post. During the 1960s and 1970s, portions of Jefferson Barracks County Park were used as a landfill. During the 1980s, an annual balloon race was held in the park. Today, because of its large size, high school cross country races are often held in the park in the fall months, most notably the Hancock Invitational.

Today, the 135-acre National Guard post at Jefferson Barracks is home to the 70th Troop Command, the Missouri National Guard's largest brigade. The post is also headquarters for the Region 7 Homeland Response Force; the Missouri Air National Guard's 157th Air Operations Group and the 10th Psychological Operations Battalion of the U.S. Army Reserve.
