The ship in the harbour right in the center of Dunkerque. Houses in the background are a bit distracting the main subject, but I could not find any better point of view for this photo.
The following information about the ship is from the website of Association des Amis de la Duchesse Anne ( http://perso.wanadoo.fr/voilier-duchesse-anne/ ) :
3-master Duchesse Anne, formerly a German training-ship
called Grossherzogin Elisabeth, built in 1901.
She was saved from scrap by the City of Dunkirk in 1981. With an overall length of 90 m, she is the biggest tall ship preserved in France. She is moored in the Dock of Commerce, next to the Musée portuaire, and can be visited.
