Chapel of Saint-Jagut, Medieval chapel in Plestin-les-Grèves, France.

The chapel of Saint-Jagut stands at the hamlet of Lézormel in Plestin-les-Grèves, Côtes-d'Armor. Rebuilt under the architect Etienne Beaumanoir of Morlaix and finished in 1496, it was consecrated in 1498. Its walls are covered with mural paintings of the late 16th century, restored, and it forms one unit with the adjoining chaplain's house.

In the 11th century Hingethen, abbot of Saint-Jacut-de-la-Mer, is said to have raised an earlier building on the site; in 1163 Pope Alexander III confirmed the abbey's possession of it. The monastery's decline in the 15th century let Guillaume de Lésormel attach the chapel to his seigneurial estate. The ruined chapel was rebuilt under the architect Etienne Beaumanoir of Morlaix, finished in 1496 and consecrated in 1498.

The chapel displays religious figures and scenes carved and painted into its walls that teach spiritual lessons. These artworks show how medieval artists communicated faith through visual storytelling.

The chapel stands at the hamlet of Lézormel, in the commune of Plestin-les-Grèves in the Côtes-d'Armor. It forms one ensemble with the adjoining chaplain's house, whose interior is separately inscribed. The chapel, its enclosure walls and floors, the calvary and the house's façades and roofs are classified as monuments historiques.

The two-faced statues now kept in the chapel are the remains of a calvary with figures that stood at the entrance to the enclosure. It was destroyed in 1793, and the chapel itself was rebuilt by the architect Étienne Beaumanoir of Morlaix and consecrated in 1498.
