Recorded Texas Historic Landmark (RTHL) designation is awarded to historic structures deemed worthy of preservation for their architectural integrity and historical associations. Authorized by the Texas Legislature under Texas Government Code, Chapter 442, RTHL is the highest honor the state can bestow on historic structures in Texas. Properties so designated are afforded a measure of legal protection and become part of the recorded history of the state's built environment.

2. Tarrant County State Bank, 332 South Main Street
