We stopped for the night in Vitré, about 40 K east of Rennes, on the way back from Brest on the western tip of Brittany one summer. We discovered a very pretty little town with a mediaeval granite castle, one of the first castles in France to be classified as a monument historique. There are many beautiful granite, slate and half-timbered houses and colourful façades, mainly in Rue de la Baudrairie. I can’t remember the name of the hotel as it was nothing outstanding, but we had a view of the castle from our window. However, we were given a very useful free Michelin guide to “secondary” towns in France that we’ve been exploring ever since.
