Another side of Rennes

I was in Rennes this week to give a guided tour. We covered the usual things - 19th century Italianate cathedral, medieval quarter, neo-classical public buildings and the famous Parliament building. All good, and remarkably quiet on the streets with the 60,000 students on vacation. In my own time I did a lot of walking to look at more modern aspects of Rennes' most interesting architectural range. Not nearly enough emphasis nor information is provided for tourists about this. I was just wondering how they managed to clean the windows at the Cité Judiciaire when the answer appeared rather startlingly. The Champs Libres is the 2006 cultural complex containing the library (glass), science museum (dome of planetarium) and ultra-modern Musée de Bretagne.
