I had a few hours before my flight and Museum Ludwig was the perfect activity to fill in that time…read more This place is massive (3 floors!), so wear your comfortable walking shoes as there is a giant staircase (elevators too of course). It's next to the main train station as well, so it's a great spot to burn time before a flight or train. I only had about 2 hours and it wasn't enough--give yourself the full afternoon or at least 3 hours! They offer a free service desk for jackets and purses. However, don't bring a large tote--they have a strict size limit and you'll have to leave it at the desk. Even if you aren't an "art person," the sheer variety here from Pop Art to Surrealism keeps it from feeling boring. Each room felt well-curated and combined with the high ceilings, there was an openness that allowed each art piece to breathe and have it's moment. Do not sleep on the gift shop. I found some nice trinkets for my desk and souvenirs for friends + family.

This a great museum to visit!! There's TONS of Picasso paintings and a couple of Warhol ones. I…read morewould say it would take a couple of hours to thoroughly go through everything, not including the special exhibit. Don't miss the rooftop! There's a couple of cool art installations there as well as a gorgeous view of Cologne Cathedral!!

I saw the storefront while walking around Cologne in the morning and thought it sounded fun. I…read morethen reserved a seat online for a later show in English. When it starts, they take you into a little theater where the setting to the experience is explained in a theatrical way and you "meet" one of the main characters, the hatter. You then go into the fictional hat shop for a demo before the VR experience. This was very cool and also poignant. You get to see what Cologne looked like before it was turned to rubble during WW2. It's not long but a neat way to experience old Cologne.

This is a great museum for maths aficionados. Captures incredible history of Arithmetic in general…read moreand its cryptographic and more sophisticated discrete maths in particular. Several exhibits and all for about three euros fee. You can spend many hours on the four floors with some original but some replicas of some of the rarest calculation machines ever built. For English users, you have enough in English in terms of supplementary cards. Must visit if you are in Bonn.

Mechanical calculators? I literally cranked out numbers in this place. The old-school calculators…read morehad hand cranks to drive the mechanism. It was a lot of fun to be able to play with some of the display calculators. Most of the calculators that you can play with come with quite detailed instructions in case you want to follow along and understand the mechanism. A beautiful space, reasonably well documented displays (even with English info), and just the right size to spend about two hours museum-ing. The focus is clearly calculating machines, but there's art as well as modern furniture on display. In some cases, the modern chairs slightly upstage the calculators. The floors are laid out such that the top floor contains the most ancient calculators and each floor down gets us closer to the present day. Worth a visit.
