Honfleur is a city in northern France's Lower Normandy region, sited on the estuary where the Seine river meets the English Channel. Its Vieux-Bassin (old harbor), lined with 16th- to 18th-century townhouses, has been a subject for artists including Claude Monet and native son Eugène Boudin. Nearby Saint Catherine's Church is a vaulted wooden structure erected by shipbuilders beginning in the mid-1400s.
