I really love this small museum. Beautiful paintings by one of the best artists, the opportunity to listen to an audio tour for free, and then have a cup of coffee in a cozy cafe nearby. The Nice Museum contains some of the best Chagall paintings, definitely worth a visit.
A great place to get acquainted with the work of Mark Zakharovich. It is better to find out everything on the spot, but here is the pinnacle of his work, if possible, be sure to visit!
The museum has a free Russian audio guide (they give a link), which greatly facilitates understanding of what is happening.
It is quite possible to walk to the museum from the shore.
