Smaller than your average Mexican city plaza, Parque Castillo is bereft of the normally standard Palacio Municipal (town hall), which sits several blocks away on Av Colón Poniente. Instead, it is watched over by the eclectic Palacio de Hierro and a 17th-century parish church, the Catedral de San Miguel Arcángel. On the south side is the neoclassical and still-functioning Teatro Ignacio de la Llave (1875), font of opera, ballet and classical music concerts.
