The Guǎngdōng Guild Hall (1907) is one of the few buildings of any genuine age in the Old Town. It’s a lovely courtyard complex, centered on a beautiful, ornate, wooden hall where popular Peking opera performances are held on Sunday afternoons (¥20 to ¥50, 2.30 to 4pm). Don't miss poking your head into the back courtyard, with its fading murals by the south entrance. It's opposite the Drum Tower, to the southeast.
