Freddy’s Pinball Paradise in Germany (near Frankfurt) is a must if you happen to be there for one of their open house events (usually once a month).

And have always wanted to go to the Hungary Pinball Museum in Budapest, but was not open when I was there …..

Budapest is an amazing city, finding pinball there also is a bonus.
And there’s a smallish but cool pinball collection in Bologna, Italy - the town where Zaccaria used to be. It’s called Spazio Tilt. Need to check opening hours. Also a very cool town in its own right….

And this place is worth a visit in Paris, mostly for older EM’s, but an incredible huge collection of EM’s going back to the original bagatelle’s. Very limited opening hours and need to make an appointment/booking to go.

And back to Germany, as mentioned earlier:
Another impressive collection with limited opening hours.
Stayed in the Medieval Madness room there lol.
