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

The organising committee is currently busy scouting locations for the Icebreaker, Galadiner etc., finding accommodation for visiting members (IBD delegates stay at the Maritim) – and preparing some pre and post tours.

Visitors not attending the IBD Meeting 2025 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 for a German annual gathering).

If you have wishes or recommendations for things you want to see, visit, taste, drink, or hear during the tours or as an event part of the IBD+, please drop us an email at ibd2025-wish-list@mensa.de.
For other topics feel free to get in touch with the organising committee by email 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
