Monet said it was not a view of the port of Le Havre at dawn, but his impression.
And behind the window of Monet's house, where he painted it, what was it?
The sun behind us, we see it shine on the sea, between boats and ships near the port, where human figures seem to appear and in the distance the city, confused between sky and sea.
