The temple has a Latin cross plan, with three naves and a ribbed vault. The main altarpiece is also Renaissance from the second half of the 16th century, influenced by Berruguete. The altarpiece consists of a bench and three bodies with three streets and four steps, finished in an attic with Calvary. On four panels of scenes of the Passion of Christ there are two reliefs with the Presentation of the Virgin in the Temple and the Adoration of the Magi that occupy both sides of the central street where a niche opens, with the hinge towards the outside, in where the beautiful image of the Virgin with the child is placed. In a chest or urn on the side of the altarpiece are preserved the capital remains of the unfortunate infants who give their name to the town.
In the entrance to the town, nearby the pont, there is the Santa Cecilia hermitage. The Romanesque doorway of the Church of Mazariegos stands out in its atrium with a beautiful cruise. It is of Gothic style with Romanesque reminiscences. It was rebuilt in the fourteenth century on a building of the twelfth century. The baptismal font is Romanesque. The altarpieces are Baroque from the seventeenth and eighteenth centuries. The altarpiece presides over the image of Santa Cecilia believed to belong to the sculptor Francisco Martínez who worked in the region around 1640.
