The Fort Tejon State Historic Park was established in 1854 by the United States of America Army. In 1858, the Fort was a station for stage coaches. It was the headquarters of the Army until 1861. California volunteer troops re-occupied the fort in 1863. On September 11, 1864 California Volunteer Calvary left it for good.

The State Park is now highly regarded by the National Register of Historic Places. The authentic structures have been restored and two of them are semi open to the public. The barracks showcases uniform sets in the quarters. The place for the commanding officer was reenacted and furnished like the original quarters.

The rooms for officers are preserved in an arrested decay state. This quarter shows the walls that are buttressed by the masons and lumber then bound together with rods. The park features the grave site of Peter Lebeck.

The Fort Tejon Historical Association presents reenactments that deal with the Civil War. The museum inside the park contains exhibits regarding the Army life and history of the locals.
