MJ things to do in Northern Europe

I'm going on a cruise in October to Northern Europe. I already have some excursions booked but I have a free day in Amsterdam, Bruges and Cherbourg each. Is there anything MJ related to do in either of these cities? Maybe a mural to see or a record store that sells his memorabilia. I'm guessing Amsterdam will be my best bet but I'm hoping the other cities will have something.
