The 18th-century former Barrack-Garrison and Parish House are noteworthy examples of civil architecture in Peñaflor.
Its layout is typical of the houses at that time, with a central courtyard and two floors. The upper level has a gallery that is used to distribute the rooms.
The façades, although very plain, represent the late Sevillian Baroque as it transitioned to the neoclassical style. Notable in the former is its carved stone entrance, while the Parish Church has a brick doorway.
