"The exhibition themed on computing technics from ancient era and early days of mechanical computing machines in modern era before the electronic calculator introduced.
Well preserved machines or their replica are interesting for all the ages particularly of the young mind. Ticket cost very little."

"Awesome and fascinating. Very well displayed, great staff , self explanatory books available in english as well. It is 4 floors, if you are curious to see how arithmatic was done in the past, you will spend a lot of time.

A must visit. Not very expensive, 8 euros family ticket, and individual 3 euros"

Chayashree Pathak

"Perhaps one of the best museums in Germany. No trip to Bonn is complete without a visit to the Arithmeum - so much to tickle your brain with - from interactive lectures on ancient computers to absolutely thrilling historical calculators which, if I had discovered earlier, may have saved me from dropping out of a mathematics degree.

Staff were incredibly kind and well-read. Getting around all the exhibitions can be a bit confusing - start from the very top and working your way down the stairs is the best way for getting about it though!

I'd recommend spending a few hours here - I was hoping to only spend an hour at most, but ended up spending ~3-4 hours since there was simply so much to do (it's especially interesting for mathematicians/academics).

I was hoping to bump into Peter Scholze but unfortunately had no luck. Maybe next time!"
