Take this opportunity to have a look at Metz: the town center is very
pleasant. The look on the bridges and islands between the Cathedral and the
Prefecture, especially the river bank are very picturesque. The gothic
cathedral is worth a look, especially four strikingly beautiful sets of
Chagall's windows.
