Honfleur is a harbour commune in the Norman department of Calvados, in France, located on the southern bank of the estuary of the Seine, very close to the exit of the Pont de Normandie. It is especially known for its old picturesque port, characterized by its houses with slate-covered frontages, painted many times by artists, including in particular Gustave Courbet, Claude Monet and Johan Jongkind, forming the école de Honfleur which contributed to the appearance of the Impressionist movement . The Sainte-Catherine church, which has a bell-tower separate from the principal building, is the largest church made out of wood of France.
