Startlingly modern for its Old Town setting, this unusual museum offers a fascinating coverage of art and history. It starts deep in an excavated rocky basement with exhibits of Neolithic flints, then sweeps you somewhat unevenly through Gallic tomb chambers, Roman mosaics and Napoleonic medals to an excellent if small art gallery. Cézanne and Picasso get a look-in while Luxembourg's Expressionist artist Joseph Kutter (1894–1941) gets a whole floor.
