In the district of Tingo, province of Luya, department of Amazonas, lies the pre-Hispanic city of Kuelap, divided into two sectors, the lower town and the upper town.

The skill and wisdom of its enigmatic inhabitants, the Sachapuyos, is evident throughout the fortress of Kuelap . They built their city on a mountain summit for purposes of controlling access and making use of the slopes as land for cultivation.

Basically, the fortified city of Kuelap consists of two gigantic human-made overlying platforms above which stands what was once the settled area. It has three entrances; two of these located at the East and the third at the opposite end of the fortress.

Its impressive defensive battlements, made out of limestone, rise 20 meters high and delimit the "lower town" and the "upper town" of this citadel.

The Lower Town consists of 335 circular structures. Standing out in the southern section is a construction resembling an inverted cone known as the "Tintero" (Ink well) and measuring 5.5 meters in height and 13.7 meters in diameter. Inside, it has a bottle-shaped chamber, which is over 5 meters deep. It is believed to have been a ceremonial construction.

The Upper Town has 80 stone constructions. The "Castillo" (Castle) and the "Torreon" (Watchtower) are the most outstanding. The former consists of three overlying platforms and is also thought to have been used for holding ceremonies. The "Torreon", in the north section of the Upper Town, is 7 meters high.
