Mundaneum 🇧🇪

Step into the fascinating legacy of knowledge management at the Mundaneum, a non-profit organization, museum, and archive located in Mons, Belgium. Originally founded in 1910 by Belgian lawyers Paul Otlet and Henri La Fontaine, this historic institution aimed to gather and classify the world's knowledge using the Universal Decimal Classification system. Long before modern technology, Otlet envisioned a world where people could access information from home using physical cards and telegraphs—a visionary concept identified as a precursor to the Internet and projects like Wikipedia.

The original initiative, which began as an enormous intellectual warehouse containing millions of index cards and documents, was once housed in Brussels before being relocated to Mons, where the modern museum opened in 1998 inside a converted 1930s department store. When you visit today, you can explore an exhibition space celebrating its groundbreaking contributions to documentation science. Android users can also enhance their visit via the Mundaneum App, which offers experiences focusing on the origins of the Internet in Europe, the 100th anniversary of a Nobel Peace Prize, and mapping knowledge.

It is an inspiring stop for anyone interested in open information and data history.
