A sober building of Neoclassic style, is the site for the offices of the City's Government and the Library and its construction started in 1928. Its façade, made of three levels, is of gray stone granite. At the main balcony on the second level there is a replica of the "Dolores Bell" (The Mexican Liberty Bell). Inside, flanking the stairways there is a wall paint made in 1979 by Carlos Sens that narrates the history of the city.
