Huaca Huallamarca is a stepped adobe pyramid in the San Isidro district of Lima, Peru, surrounded today by the residential blocks of one of the city's wealthiest neighborhoods. The mound was built by the Maranga culture beginning around 200 CE and continued in use through later Ychsma and Inca occupation in the 15th century. It rises roughly 18 metres in successive terraces of small mud bricks called adobitos, individually shaped and stacked in patterned courses. Arturo Jimenez Borja directed the major restoration of the platform between 1958 and 1960, controversially reshaping the eroded summit into a smooth ramped silhouette that does not match the original profile. Burials recovered from the upper terraces include Ychsma-period mummies wrapped in cotton textiles and accompanied by ceramic offerings and weaving tools.
Huaca Huallamarca operates today as a small site museum surrounded by apartment towers, the adobe terraces glowing pale orange against the surrounding glass facades after sunset.
