It is constructed of native stone from two local quarries and houses the county government. The Heart of Texas Historical Museum is housed in the old McCulloch County Jail. The three-story structure served as the county's correctional facility until 1974, when it was deeded to the Heart of Texas Historical Museum. The restoration of this Santa Fe train depot is unequaled. Located in the lovely landscaped setting of North Bridge and Depot Streets are the art gallery and studio of renowned artist Francis King.
Visitors are welcome, and the center is available for parties and small conventions.
