Atriangular and sloping plot with a high visibility was the site chosen for this chapel, where the project considered the possibility of celebrating masses both indoors and outdoors.

Two works inspired the authors: the church of São Pedro das Águias in Tabuaço (Portugal), and the chapel of Notre Dame du Haut in Ronchamp (France), by Le Corbusier. São Pedro, a Romanic church of the 12th century by the Tavora River, is exemplary in its adaptation to the environment and for its spatial richness in spite of its small scale; Notre Dame du Haut, for its part, is one of the most representative buildings of the 20th century, and a model both for the use of natural light and for the multipurpose use of a facility of these characteristics.

This church extracts lessons from both buildings. The entrance, on the west side, gives access to a small chapel devoted to Santa Ana. Behind it is the main shed, dotted by a series of small rectangular openings that bring natural light into the hall. On one of its sides, a stair rises to a pulpit that looks out to the exterior, facing a staggered plaza for outdoor celebrations during local festivities. Serene and bright, the chapel becomes a gathering point for the community.
