Pirca Pirca (possibly from Quechua pirqa wall) is an archaeological site in Peru. It is located in the La Libertad Region, Bolívar Province, Uchumarca District. Pirca Pirca was declared a National Cultural Heritage of Peru by the National Institute of Culture by Resolución Directoral Nacional No. 075-INC on December 30, 1998. The site lies on top of the mountain named Pirca Pirca.

Pirca Pirca, perched on a hill overlooking the Chivane River in Peru's La Libertad region, is a captivating archaeological site whispering tales of ancient civilizations and forgotten rituals. Its history unfolds like a layered tapestry, revealing the fascinating story of its inhabitants across centuries.

The earliest whispers of human presence at Pirca Pirca date back to around 800–200 BC, during the enigmatic Chavín culture. Renowned for their exquisitely carved stone stelae and complex religious practices, the Chavín likely used Pirca Pirca for ceremonial purposes. The site's alignment with celestial bodies and the presence of carved stones suggests its use as an astronomical observatory.

As the Chavín culture waned, the Wari rose to prominence around 600–1100 AD. They transformed Pirca Pirca, constructing imposing stone walls and platforms that still stand testament to their engineering prowess. The Wari likely used Pirca Pirca as a strategic administrative center, controlling trade and communication routes.

Around 1000–1476 AD, the Chimú culture, known for their intricate ceramics and maritime prowess, left their mark on Pirca Pirca. They added their own architectural styles, incorporating trapezoidal doors and niches into the existing structures. The Chimú likely used Pirca Pirca as a regional center, facilitating trade and showcasing their cultural influence.

The Spanish conquest in the 16th century marked a turning point for Pirca Pirca. The site was largely abandoned, and its importance dwindled. However, in the early 20th century, archaeologists began to rediscover Pirca Pirca, unearthing a wealth of artifacts and shedding light on its fascinating past.

Today, Pirca Pirca stands as a silent witness to the rise and fall of cultures. It serves as a cultural treasure, offering visitors a unique opportunity to connect with the rich history of Peru and gain insights into the lives of those who once inhabited this land.
