Borden County Jail was built of hand-hewn native stone from Gail Mountain and was planned for maximum security. It is one of the oldest jails in use in West Texas. Diebold Safe and Lock Co. was awarded the $4,500 contract in 1896. Behind two-foot-thick outside walls, the cell walls and floor are of 1/3-inch case-hardened steel plates, impervious to hacksaw blades. Doors fastened with huge hasps and padlocks opened by a six-inch key.
