Jefferson Barracks, established in 1826 as the country’s first Infantry School of Practice, served as a major military installation until 1946. Named in honor of President Thomas Jefferson, the post played an important role in westward expansion. Jefferson Barracks served as a gathering point for troops and supplies bound for service in the Mexican War, the Civil War, various American Indian conflicts, the Spanish-American War, the Philippine War, World War I and World War II.

The site is now a St. Louis County Park with a mission to preserve St. Louis military history through educational programs, tours, special events and exhibits. The park's three museum contain artifacts from this historic site. The Powder Magazine Museum houses an exhibit covering the history of Jefferson Barracks from 1826 until it was closed as an active Army installation in 1946. The Old Ordinance Room Museum contains rotating exhibits on military history from 1826 to 1946. The Laborors House was built in 1851 to house the laborors who constructed the buildings on the post. Closed in January.
