The current Municipal Palace is of Ionic architectural style and occupies part of the site of the old "Colegio Grande del Seminario de los Padres Paulinos" (Grand Seminary College for Pauline Priests) who had to abandon the city in 1860 [REF].
This arch (Arco de la Calzada de los Héroes, in Spanish), topped by a bronze lion, began construction in 1896 and has been modified a number of times since then.
