The wide plains that make up the 300-hectare (740-acre) Santuario Histórico Pampas de Ayacucho are scattered with relics of the Huari culture, which evolved 500 years before that of the Inca. Huari was its capital, thought to have once been home to 60,000 or more residents, and its surrounding fields contain a maze of tumbled stone temples, homes, and 12-meter (39-foot) walls. This is believed to have been the first urban walled settlement in the Andes, created by a civilization whose livelihood was based on such metalworking feats as bronze weapons and gold and silver jewelry. A small museum displays skeleton bits and samples of ceramics and textiles; opening times are at the whim of the workers. You can get here cheaply from Barrio Magdalena in Ayacucho via irregular buses, which continue to Quinua and Huanta for S/5. Most travel agents in town offer guided tours to the site for around S/60.
