Chapel of Our Lady of Grace, Honfleur

This 17th-century pilgrimage chapel stands on the Plateau de Grâce overlooking Honfleur, built between 1600-1615 by sailors and townspeople on land donated by the Duchess of Montpensier. The site's spiritual significance dates back to 1023 when Duke Richard II of Normandy founded an earlier chapel here after surviving a storm at sea. The interior houses one of France's most impressive collections of maritime ex-votos, including ship models suspended from the vaulted ceiling, marble plaques, and paintings from grateful sailors.
