The University of Bonn, established in 1697, is home to a variety of new and old museums and collections.
One of the newest and most interesting - especially for those interested in the science and technology of numbers - is the Arithmeum, a fascinating museum dedicated to mathematics.
Based upon a collection of 1,200 antique calculating machines and rare books on the subject dating back many centuries, the museum is also notable for its spectacular steel and glass structure, designed to represent "the transparency of science."
