The Casilla del Caminero, as the oldest structure in the campus is popularly called, suffered damages from the San Fermín earthquake, which occurred on 11 October 1918. Two years later, on 1920, the structure was repaired by installing "a system of internal rods screwed into exterior plates which tied and stabilized the walls." Additionally, "the shed wall was extended up using materials so alike to the original that in antique photographs it seems like an original wall; however, the project plan reveals that this is not the case." The "[C]asilla suffered more changes later, which included the addition of a portico of concrete, which was eliminated when the casilla was moved, and of an eave over a lateral window converted into a door," which was destroyed when a tree that was permitted to grow inside the "Casilla" collapsed as a result of the Hurricane María winds.
