This chapel holds the patron of the village, the Virgen de Belén. She can be found some three kilometres from the built-up area alongside the River Ruecas, surrounded by quartzite rock walls, which makes a natural passage on the way to Guadalupe. Within its walls, and in the paintings which decorate its apse, the passing centuries have combined Mudejar, baroque, and rococo styles to give rise to a most unusual image. This is a outstanding building with a historical, artistic, and heritage value complemented by its exceptional surroundings.

This small Mudejar chapel is located on the way to the Real Monasterio de Guadalupe shortly before the hill of the Puerto Llano in the so-called Valley of Belén.

It has undergone extensions to the original construction and consists of a single rectangular nave and a curious hexagonal apse.

The whole of the exterior construction is of stone with the exception of the arrises of the apse and its windows, which are of brick. This gives the ensemble an austere and sober appearance.

The nave which occupies the whole of the interior consists of a succession of brick arches which start at ground level and support the longitudinal barrel vault. The whole of the interior is clean and white with the exception of the last section of the vault and the area of the transept which show profuse ornamentation. On the transept there is an exceptional ensemble of 17th-century baroque friezes on which stand out astral elements such as the sun or the moon and various plant motifs, decorations based on leaves of acanthus, and allegories such as that of the Tree of Life.

On the decorated part of the cannon vault there are more paintings although these are of a later date, to be precise from the late 18th century. In this case the frescoes are rococo in style and represent cherubs with musical instruments, plant motifs, etc.

Attached to the chapel stands the Casa del Santero which was the house of the person who looked after the building. In exchange for this he could cultivate a kitchen garden owned by the chapel as well as live in the house.

The interior of the ensemble is also noted for the carving of the Madonna and Child as some of its elements are unusual. It is Gothic in style and thought to be of the 15th century; it is of polychrome cedar wood. She wears a tunic with a V-neckline and geometrical and plant adornments much to the taste of the time. She has suffered various mutilations and restorations; the last of the latter uncovered the crown now to be seen in this image of the Madonna. Twice a year the chapel opens its doors to the people of Cañamero. The first is on 24th January when the young lads hold a festival to celebrate their coming of age. The second is on Easter Monday which is when Cañamero celebrates its main feast day which is attended by the whole village.
