The church of St. Mary of Guardão, once dedicated to Our Lady of the Assumption, has undergone some transformations over time. However, its original layout fits within the canons of the Romanesque style, from the 12th century, as evidenced by the structural elements of the religious temple. The portal is defined by a round-turned arch, with no decorative elements.

The medieval bell tower, which stands in the center of the façade, has two windows ending in a perfect arch similar to the portal. The triangular profile of its finish bears a cross patté. The body of the church has been altered, with the left elevation having an attachment that functions as a sacristy. The right elevation shows the moving of the side door, the result of the temple's increase in length and height. In this elevation, you can also see two podomorphs (prehistoric art) engraved on a granite block on the wall.

The interior of the church is simple and rectilinear, interrupted by the baptistery, with the transition from the body of the church to the chancel marked by the crossing. The reredos, in the back, was made according to the rules of the neoclassical style during the 19th century. It is composed of columns with smooth shafts, painted in a green shade. In the alcoves, that open in the intercolumniations, there are images of Saint Blaise and of Our Lady of the Milk from the 16th century. In the middle of the stand is the image of Our Lady of Miracles. The central chamber is flanked by pedestals with images of St. John and St. Anthony.

On the left side of the nave, in a round arch, is the baptismal font in front of a small altarpiece that houses the Blessed Sacrament.
