The interior walls are 15-inches thick and made of brick. Hays County's only official hanging was held in the jail yard on April 19, 1915. The jail lasted until 1937 when frequent breakouts and repairs necessitated a new one. Listed on the National Register of Historic Places, this structure will soon be renovated into a Law Enforcement Museum. The atmosphere is reminiscent of the decades when these businesses were central to the community.
Several features distinguish the interior.
A wooden loft is reached by wooden stairs. Wooden floors, an original safe, open beamed ceilings and a original floor scale are still in place. Large sliding doors were placed exactly the distance apart as the openings of railroad cars to facilitate unloading. Deliveries arrived via railroad and unloaded at the spur that ran along side of the building. For many years, the building housed King Feed Company.
