The chapel of Saint-Jean-Baptisteau is the only one of Charmey's current nine chapels, out of the original eleven, to have retained its cycle depicting the life of a saint, painted for the edification of believers during the Catholic reform of the 17th century. It corresponds to the type of mountain chapel with which the parish of Charmey was blessed in large numbers, with eight 17th-century foundations, two of which were rebuilt on a medieval structure.

The architecture is simple and modest, with a gable roof topped by a bell tower and forming a canopy protecting an arched doorway. Inside, a longitudinally planked vaulted ceiling follows the medieval tradition. The benches have baroque cheeks. The materials used come from the valley: river pebble walls plastered with lime, grey limestone floors and door and window frames, wooden ceilings, pews and liturgical furniture, and tavillon roofing.

Founded in 1633 by Louis Fragnière, a Gruyère cheese merchant, and restored in 1989 to a state close to that of the 17th century, the Saint-Jean-Baptiste chapel is particularly remarkable for its Annunciation on the chevet wall and above all for its frieze depicting fifteen scenes from the life of John the Baptist.

The altarpiece, dating from 1635, is dedicated to Saint John the Baptist, flanked by Saint Louis, patron saint of the founder, and Saint Roc, patron saint of the plague victims who were invoked during the plague that swept through the valley in 1634. The whole structure is made of fir wood painted in faux-wood and gilded with bronze. The arched arcades separating the three saints and the arched frame surrounding the Virgin and Child were added in the 19th century.
