Church of Saint-Jean-le-Rond, Paris
4th arrondissement of Paris, France
The Church of Saint-Jean-le-Rond, Paris (Église Saint-Jean-le-Rond de Paris) was a small church originally attached to the north side of the Cathedral of Notre-Dame de Paris near the west front, and close to the entrance of the cloister. It was built earlier than Notre-Dame, at about the same time as the church which preceded Notre-Dame, the Cathedral of Saint-Etienne. It was dedicated to John the Baptist, and was used primarily as a baptistry. It survived centuries longer than the Cathedral of Saint Etienne, but was finally demolished in the early 18th century to make room for a new street, the rue du Cloître-Notre-Dame.
