By necessity, our trip to Paris will fall over Easter weekend. In general, what we can expect in terms of museum, other tourist site closings?
Sites should be open, but remember ,, churches ( NOtre Dame, Ste Chappelle, and Sacre Couer etc. etc) will definately be either closed for sightseeing or open very short hours. Easter is considered the most important Christian holiday, and most churches will have services all day.
Perhaps some sites will have shorter hours.
