Behind the Cathedral is the Plaza Liberación, with the Teatro Degollado (deh-goh-yah-doh) on the opposite side. This neoclassical 19th-century opera house was named for Santos Degollado, a local patriot who fought with Juárez against Maximilian and the French. Apollo and the nine muses decorate the theater's pediment, and the interior is famous for both the acoustics and the rich decoration. It hosts a variety of performances during the year, including the Ballet Folclórico on Sunday at 10am. It's open Monday through Friday from 10am to 2pm and during performances.
