Built at the beginning of the century to use it as a shelter for the person  in charge of the park Porfirio Díaz. The Castillito is entirely built with compressed brick elaborated in Cuernavaca in an ultra modern factory for those times. It was recovered by the state governor Vicente Estrada Cajigal in 1986 and assigned as the Seat of the Municipal Consultive Council and the Photographic Museum of the City. Their small rooms have furniture of the time and exhibit in a pleasant atmosphere some of the oldest photographs of the city.
