Fodor's Expert Review Huaca Huallamarca

This mud-brick pyramid, thought to be a place of worship, predates the Incas. Painstakingly restored on the front side, it seems out of place among the neighborhood's upscale homes and apartment buildings. Here you'll find a small museum with displays of objects found at the site, including several mummies. From the upper platform you can take in views of San Isidro.
