I am spending the week-end in Reims for my birthday, and my wife set up a visit of the caves of Ruinart, a very old Champagne house. Very unexpected (what we visited I mean; I knew where we were going). Thye have kilometers and kilometers of underground caves - which originated as clay mines in Roman times, and are now ideal for Champagne, with constant temperatures and high humidity.
We also visited the Cathédrale, which is very impressive and has spectacular vitraux (how's that in English? Glassworks?) by Chagall - made in 1971, and by other modern artists.
I'll try to do a "tourism blogging" diary when I get back. In the long run, we're all dead. John Maynard Keynes
I was surprised by all the Tudor architecture in Reims. I also had a difficult time pronouncing the city's name.
