The municipal palace was built during the railroad boom in the early 20th century. Covering an entire side of the main plaza, it today towers over the other buildings in the center. It is built in provincial Neoclassical style with massive columns and arches. However, the back of the structure is very different, as it is an irregular pattern of brickwork, which looks like it has half collapsed. In reality, the structure was never completed. Since 1906, the city has promised to finish the building, but never has. Even the federal government in 1975 announced plans to not only finish the building but restore many of the churches and plazas, but they never came to fruition.
