I've learned that the first two days of our upcoming trip to Paris will be during European Heritage Days in France. I've read some very general information which states that museums/monuments (or at least some) are free during these days and that many non-public sites are open to the public (again for free) but I'm having a very hard time finding more information as to exactly which monuments are free/sites open in English. The official French site's home page can be translated but not the imbedded links. Has anyone been there during these days in the past and can give me a summary of what museums/monuments are free and any suggestions on 1-3 non-public sites that are must see? I'm not concerned about saving money on the museums, I just don't want to buy a 4 day museum pass unnecessarily. I've also read the lines for the non-public sites can be very long which is why I'm just looking for a couple.
Thanks!
