Prehistoric
Prehistoric evidence on rocky walls includes the rock paintings of Chiñuña-Yamón and Limones-Calpón in the province of Utcubamba. Some of these haughty pictorial samples were made by people who had a hunting economy 6 or 7 thousand years ago.
By the time the Peruvian civilization was already formed, there appeared a type of ceramics mainly identified in Bagua.
Historic
There are many architectural remains from the Chachapoya culture such as Kuelap, Gran Vilaya, Cerro Olán, Purum Llaqta, Cheto, Gran Pajatén, etc. All these structures appear to be related, but their age and order of construction are unknown.
