Saint Erasmus Chapel or Grimmen Chapel

Built between the 12th and 13th centuries, this chapel reflects its era with five original Romanesque windows still visible. Over the centuries, it suffered significant damage and was rebuilt several times. During the Revolution, it was converted into a prison, and a tree of liberty was planted nearby in 1793. Inside, there is a 15th-century statue of the Virgin, a head of Saint John, and a bust of Saint Anne.
