Here is a teaser indicating events we are preparing for you. This list is extensive but neither final nor complete since there are still events in the making and some not quite finished (and thus subject to change) and some even do not show here yet since if we're still wainting for the final "ok" before we may present them on here - so expect the event lists below to grow in the next weeks.

By clicking on the small triangles at the left you can unfold the list of tours or events by location, category, or date.... or click on "Expand" in a title to expand all for that part; "Collapse" reverses that obviously.

The main venue is the Maritim Hotel Düsseldorf, Maritim-Platz 1, 40474 Düsseldorf, Google Maps.
The hotel is located within walking distance of Düsseldorf international airport (IATA code DUS) and just a quarter of an hour from Düsseldorf main railway station using local trains.

Visitors not attending the IBD Meeting 2025 itself will be offered the odd** event like presentations, sightseeing, company tours, cultural events, games, talks, tastings, cozy hours, get-togethers and much more (a bit like a German Mensa annual gathering).

If you have wishes, recommendations for things you want to see, visit, taste, drink, or hear as part of the IBD+, or want to offer your support, or just have a question please drop us an email at ibd2025@mensa.de.

+ The plus indicates that we will offer quite a few events for visitors in addition to pre and post tours.
* The International Board of Directors meeting (IBD) is the general meeting of the worldwide leadership of Mensa.
** Well, quite a few events as a matter of fact
