The Abbey of St. Remi is less well known than the Notre Dame Cathedral, but definitely merits a visit if you are going to Reims for more than a few hours. Although it's not in the center of town, it is an easy bus ride away and if you have good walking shoes, easily reached on foot from downtown.
The remains of St. Remi are here along with several other dignitaries.

The peaceful beauty of this abbey is evident the moment you enter, but there is a reminder on the ground :)
