The spaces of the Alcázar are set with furniture, domestic utensils, jewels, paintings and other objects belonging, on the ground floor, to the time when the Castle was inhabited by the emperors Maximiliano and Carlota (1864-1867); and on the top floor, at the time when President Porfirio Díaz and his wife Carmen Romero Rubio occupied the building as a summer house (1883-1910).

In addition to the acclimated rooms, in this area of the Castle there is a room dedicated to the Battle of Chapultepec (1847). On the exteriors stand the Caballero Alto and the gardens designed from the descriptions that were made of the garden during the time of Maximilian.
