As in the case of Roque Bentayga, we find another of the emblematic fortresses of the ancient Canarian people. Roque de Cuevas del Rey is different from Roque Bentayga as all the existing caves are entirely artificial. Out of the entire troglodyte complex, it is undoubtedly the part dug out on the north face that is the steepest and most impregnable. The caves are divided into five levels or platforms communicating with each other by way of narrow paths and stairs that were also carved into the rock.

What is surprising is the perfection and arduousness of the task to carve out these caves, with a perfect shaping of its walls, ceilings and floors. Some of the floors are cross-shaped, others rectangular or square, with rooms on the sides. The entrance openings bear signs of closing mechanisms to fit wooden doors rotating on hinges. Many of these rooms are decorated with pictorial motifs, and the main colours used were red and white, obtained from mineral pigments.

This elaborate troglodyte complex is intimately related to the control and management of the numerous silos that were excavated at the site. It houses a huge communal granary which is mainly located on levels III and V of the north face.

Especially important is the Cueva del Rey or del Guayre cave, which is extremely large and consists of a vaulted ceiling and quadrangular floor with two rooms on the left that have painted frames. The floor of the main chamber has a complex system of bowls of different sizes but more or less circular in shape and always distributed around a large central bowl. The three walls of the main chamber were painted with white pigment on the lower third. Circular symbols are preserved here, aligned with what was a pictorial composition that included red circles.
