The City Museum (Museo de la Ciudad) was until recently the municipal government building. The structure was built in the 19th century, but contains many elements from the architecture of the previous century. It originally was called the Escárzaga Palace, the residence of mine owner Pedro Escárzaga Corral. The building is of lime and sandstone on the exterior walls with the interior paved with adobe and stone. The current tile floors are a recent addition. The roof is of reinforced concrete, which replaced the previous one made of packed earth and wood beams. Only the main terrace is left completely intact in its original condition. The building was a copy of a hotel in France. The building currently contains a mural of the city's history done by Francisco Montoya de la Cruz in 1954. From 1930 to 2008, it served as the municipal hall, when it was converted to its current museum status. The museum has a collection of movie posters, film scenes and equipment.
