The schoolhouse and chapel was completed and dedicated on February 22, 1879, making it the last permanent structure to be completed during its military career. The chapel is built like the Officers' Quarters, and in fact its site was first intended to be another duplex. Funding was only sufficient for the foundation of the kitchen to be completed, so the building was finished as the present schoolhouse and chapel. After the US Army left, the building continued functioning as a schoolhouse, and at one point, a private home. The Fort Concho Museum purchased the schoolhouse in 1946 and restored with funds raised by US military personnel on nearby Goodfellow Air Force Base.
