If you only had one afternoon to spend in Paris, the Rodin Museum on Rue de Varenne (Gallery IV) might be the place to spend it. It's in an old mansion where Rodin actually once lived and worked (in rented rooms) and offers a fascinating journey through his artistic life. A huge bonus: the museum is surrounded by three acres of beautiful gardens filled with some of Rodin's biggest, most expressive sculptures, including The Thinker, The Burghers of Calais, Balzac, The Gates of Hell and The Shades. It's a serene, expansive place -- you could easily spend a couple of hours wandering around, relaxing on the benches and even having a bite in the small cafe. Best of all, you can do this for the grand sum of one Euro -- it might be the best bargain in Paris. (One Euro gets you into the gardens only -- the Museum and gardens combined cost six Euros, still a deal by Paris standards.)
