IF YOU ARRIVE SOON ENOUGH, OR BEFORE LEAVING

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.
