The Leon Valley Historical Society began as the Leon Valley Pageant Association in 1973 to commemorate Leon Valley's early history with a Stagecoach Days Parade and other events. Over the years the organization has evolved to focus on the history of our community and surrounding areas in northwest Bexar County. The name "Leon Valley Historical Society" is an assumed name, certified by the State of Texas.

Currently we are investigating and restoring the Huebner-Onion Homestead and Stagecoach Stop, a two story structure along Bandera road that dates to the 1850s, listed in the National Register of Historic Places and a Texas Historic Landmark.

In collaboration with the City of Leon Valley, we have created a natural area park out of a 36-acre parcel of land adjacent to the Homestead, which was formerly part of the original Homestead property. With primitive trails to view plants, birds and other wildlife, and serving as an outdoor classroom, the Huebner-Onion Natural Area is a green oasis in the middle of an urban landscape.

The Society maintains a local history collection in the Kenneth & Esther Alley Historical Collection at the Leon Valley Public Library.
