Built starting in 1444, the Collegiate Church of Saint Rémy was listed as a historical monument in 1930. Above the door, the inscription "Verbum Domini Manet In Aeternum," meaning "The Word of God is eternal," is the motto of Protestants. The church features the tombstone of Henry the Elder, 16th-century stained-glass windows, an organ purchased from the Benedictine Abbey of Vergaville in 1792, and remarkable tombstones. The Paschal Lamb and monstrance appearing on the tombs are the distinctive symbols of membership in the Confraternity of the Blessed Sacrament (merchants, clerks, judges, and officers). Guided tours are available.
