As the result of a siege, the Alcázar was reduced to a ruin during the Spanish Civil War. After the war the Infantry Academy was provisionally installed in Zaragoza, at the building of the Military General Academy, and in Guadalajara, San Diego de Alcalá Foundation headquarters. During 1948 - 1949, the academy returned to Toledo, to a new building, which was the work of the military engineers Lieutenant Colonel Manuel Carrasco Cadenas, Lieutenant Colonel Arturo Ureña Escario, and Lieutenant Colonel Julio Hernández García. The building, constructed in Neo-Renaissance and Neo-Herrerian style, harmonizes well with the Alcázar, located on the opposite side of the River Tagus.
