Perched on a spur housing both a 13th-century castle, the last ruins of which were visible until the early 20th century, and a place of worship, the church forms a landscape celebrated by many painters and writers, including Louis Veuillot.

Charmey became a separate parish from the mother parish of Broc in 1228. Rebuilt in 1567 with five altars, the church was given its bell tower-porch in 1673 before being rebuilt again in 1738, giving it its current Baroque appearance, with the exception of the choir, which was enlarged in 1938.

Outside, on the east side, is the so-called old chapel, founded in 1501, with the tombs of former parish priests and an 18th-century ossuary. A grotto dedicated to Notre-Dame de Lourdes has been dug below, donated by the Italian entrepreneur Albinati during the Belle Époque.

Inside, the floor of the nave slopes slightly upwards. The high altar in La Roche marble, dedicated to the patron saint of the parish, Saint Laurent, and the two side altars were completed in 1883. The remarkable pulpit is one of the oldest in the canton. The choir windows depict Saint Nicolas de Flüe, the Virgin of Fatima, the Sacred Heart and Saint Canisius. They were made by the glassmaker Jules Schmid between 1938 and 1944.

The organ case, of great nobility, comes from an instrument at the Cistercian abbey of Salem, near Constance, which was moved several times before being taken over by Aloys Mooser. The parish of Charmey acquired the instrument in 1845 and commissioned Moritz Mooser, son of Aloys, to adapt it to the church gallery.
