The simplicity of the exterior of the Church of San Biagio di Baver contrasts with the richness of the late 15th-century frescoes preserved in the apse. In the arch above, the Annunciation introduces the visitor, while in the lower arch, the six prophets recall the prophecies of the Old Testament. At the center of the back wall, the Crucifixion dominates: Christ in the foreground on the cross, the two thieves behind, and in the background, Jerusalem surrounded by walls.
The scene is animated by numerous details: the pious women, knights and Roman soldiers gambling for Jesus' garments, horses all different from one another, Eastern-style domes, a flock of birds, and the angel and devil accompanying the death of the thieves. Particularly intense is the face of Christ, marked by pain, which reappears glorious and blessing among the group of apostles at the base.
On the side walls, the martyrdom of Saint Biagio, bishop of Sebaste and 4th-century martyr, is depicted, from the trial to glorification in heaven. A holy helper against sore throats, Saint Biagio is accompanied by other protective figures: Saint Sebastian and Saint Roch against epidemics, and Saint Apollonia for toothache. On the vaults of the ceiling, the four Fathers of the Western Church appear.
The apse, with a Gothic structure, adjoins a Renaissance nave, which preserves a votive fresco from 1542 and a 19th-century altarpiece featuring the Madonna and saints Peter, Biagio, and Lawrence. Outside, the rope for ringing the bell is still visible, linked to a tradition that comes alive every year on February 3rd, the feast of Saint Biagio.
