Huaca del Dragon, also called Huaca el Arco Iris, is a Chimu adobe platform on the northern outskirts of Trujillo, Peru, built around 1100 CE during the early period of the Chimu state under the kingdom of Chimor. The structure is a roughly square enclosure 30 metres on a side, with an interior ramp leading to an upper platform, and is most recognized for the relief friezes that ring the inner walls. The friezes depict a repeated rainbow-arch motif framing two-headed serpent figures and small dancing human attendants — interpreted as fertility and water symbolism tied to the agricultural cycle of the Moche Valley. The site was first cleared and consolidated in 1963 under the direction of Jorge Zevallos Quinones. Modern conservation has stabilized the friezes under a fabric canopy that filters sunlight to prevent further pigment fading.
The serpent reliefs face outward in continuous procession, each pair mirrored across the doorway lintels.
