Housed in a very grand structure flung up in 1870, Rouen’s simply outstanding fine-arts museum features canvases by Rubens, Modigliani, Pissarro, Renoir, Sisley (lots) and, of course, several works by Monet, as well as a fine collection of Flemish oils. There's also one jaw-dropping painting by Caravaggio as well as a very serene cafe. Drop your bag in the lockers provided and follow the route through the galleries, arranged chronologically.
