Olan

Olan is a large Chachapoya settlement in the mountains east of the Utcubamba Valley. Its many circular stone buildings bear geometric friezes, including zigzags and diamond patterns, that distinguish the architecture of this region. The settlement belongs to a network of hilltop places built by the Chachapoya before the Inca conquest, amid the steep valleys and cloud forests of the northern Andes.

The later city of Chachapoyas lies here.
