This building was constructed in the 18th century.

The beautiful murals by Octavio Ocampo, located on the sides of the staircase, stand out. 

These pictorial works depict the faces of some of the heroes of Independence and the Revolution. On the ceilings, you can appreciate events and characters from Mexican history, including the conspiracy of Querétaro and the Abrazo de Acatempan.

Inside the building, you can also see busts of figures like Venustiano Carranza and Álvaro Obregón, as well as the coat of arms of Celaya crafted by local artisans.
