Paramonga Fortess

Paramonga was an important city constructed at the border of the former Kingdom of Chimor in Peru during the late Intermediate Period, whose capital was the metropolis of Chan Chan.

Paramonga is located on the Fortaleza River, close to the town of Pativilca to the north of Lima. It is said that it was an important religious settlement, similar to Pachacamac. It is named after the nearby modern town of Paramonga, as its original name is unknown. Paramonga is often called a fortress due to its staggered pyramid of four levels of enormous proportions constructed on a hill, which somewhat resembles a European medieval castle, though it was built prior to Spanish colonization of the area.
