[4] The Fortress of Piruro II can be found on the right side of the river Tantamayo over 3.8 km above sea level.

The fortress is composed of walls built with stones hewn in squared shape and uniform size.

At the center of this area, there are remnants of a stone and mud structure that are partially buried underground.

Currently the building is enclosed by stone walls measuring approximately 1 1/2 meters in height.

This tower is situated near a section of the structure's rear where some stones bulge out, that were used as a makeshift ladder.
