Huaca San Borja, Pre-Columbian archaeological site in San Borja, Lima, Peru.
Huaca San Borja is a stepped mud brick pyramid sitting in the middle of the residential district of San Borja, in Lima. The structure is made up of several platforms stacked on top of each other, built from compacted earth and adobe blocks that are still clearly visible today.
The Ichma people built this complex between the 10th and 15th centuries, using it as a ceremonial and administrative center. The Inca later absorbed it into their expanding territory, and it remained in use until Spanish colonization changed the region entirely.
The word "huaca" comes from Quechua and refers to a sacred place or object believed to hold special power. Local schools bring students here regularly, making it one of the few ancient sites in Lima that serves as a living classroom.
The site is in a residential area and easy to reach on foot from the surrounding streets. A local guide is worth hiring since the structures can be hard to read without context, and guides often know which parts are currently open to visitors.
Each new phase of construction was built directly over the previous one, completely sealing it rather than tearing it down. This means older layers are still intact inside the mound, preserved beneath the surface and not yet fully studied.
