Lyon is Grenoble's closest neighbouring city, and also the second biggest city in France after Paris. Every year, a little before Christmas, it also hosts a light festival: the fête de lumières. I went with a couple of friends on a day trip organised by our university, during which we ran away from a guided tour (snore) and spent a lot of time in various pubs. I would have liked a bit more time to explore Lyon because what I saw of it was rather lovely.
The inside of the basilica was breath-taking: astonishingly elaborate baroque ornamentation on every surface with these enormous stained glass windows. I have great love for cathedrals, especially the stained glass.
