This temple has the main characteristic of being “magnificent,” as a creation that is a symbol of the historical facts that occurred on that site. The project belongs to the architect Juan Martínez, winner of the contest called in 1943.

From the exterior one can observe a monumental building of structured concrete measuring ninety meters that can be seen from far away, proceeded by a large plain area surrounded by a lateral colonnade, crowned by a large tower that ends in a point and that is accompanied on its lateral side by two terraced structures. The interior space is different from the interior space that is rather smaller in comparison to the total structure. The cathedral-like verticality of the entrance is indicated by a double stairway with 12 steps, large metal doors, the largest measuring eight meters, decorated with colored glass mosaics that with the exterior light rays, add a diversity of tones to the building interior.

In the interior there is an internal space developed with a radial layout having three naves, a central one and two lateral ones. These, in turn, are divided by parabolic arches. The central nave has the largest arch. In the first part of the construction there is a large convex roof decorated with coffers that go from the finishing point of the parabolic arches towards the top part linked with the main entrance tower. This provides an even more monumental sight perspective from the lower part of the temple.

The central radial nave has its culminating point in the curved high altar, surrounded by the flags of Latin America, which is geometrically the central point of the radius. It is crowned by the image of the Virgin del Carmen, Patron Saint of Chile, finished off architectonically with a parabolic arch.

Before the zone of the presbytery, there is a curved transept that is integrated to the formal radial union of the naves and there are devotional altars in its two ends. The transept, i.e. the union of the transept with the central and lateral naves, is also crowned with parabolic arches.

The high altar is surrounded in its exterior, on both sides, by a curved stairway that leads to the figure of the Virgin del Carmen located in the top part of the altar. From this point one can appreciate only a few meters away the sculptural figure and there is a panoramic view of the temple crowned by a large stained glass window. The curves formed by the staircase leading to the Virgin del Carmen and the one to the transept form a Mandorla layout, or a mystic almond arm, a sacred symbol of the religious iconography dating from the Medieval Period.

Without a doubt the temple has three significant attractions: the external monumental architecture, the interior development based on curves and parabolic arches and the great decorative work of the stained glass windows of the entrance, which give the historical place the identity and importance in which it is located.
