The ancient Kuelap fortress – in the Amazonas region in the north of the country - was built and developed between the 6th and 16th centuries by the Chachapoyas culture and lies on a ridge overlooking the Utcubamba Valley.

Known as the Warriors of the Clouds, the Chachapoyas people created the largest stone structure in South America, which contains around 450 houses - topped with thatched roofs and decorated with zig-zag and rhomboid friezes - ringed by walls up to 60ft high and pre-dating Machu Picchu by some 800 years.
Kuelap was lost in the cloud forest for three centuries until it was rediscovered in 1843 - echoing the hit Charlie Hunnam - Robert Pattinson Amazon adventure movie The Lost City of Z - and then declared a cultural heritage site in 2003.
