Directions for (e.g. ordering food to) the location:
 Staatliche Hochschule für Gestaltung (HfG)

 Baden-Württemberg, Germany

Direct orders to: Info Desk in the inner court. Best, you also add your DECT number. Maybe take a look at how to get to the location

  • Building: This building is listed for preservation. It used to be a weapons factory during WW I. Please consider this when you are inside and around the building. For those who are more curious about the building; take a look at Hall Constructions - Hall A.

Donations, Merch

We have a free entry policy. Yet, organising the GPN comes at a cost. To cover those costs we kindly ask for a voluntary donation of 30€, plus 5€ if you registered for the KVV Kombiticket.

If you're enthousiastic about making a donation prior to the event we are extremely grateful. This year, are especially grateful about before-event donations because we carry a high financial risk for hosting the GPN. You can find our banking details here.

T-Shirts / Hoodies

Buying merch helps to financially support the event.

Pricing / Reservations

  • Pricing: T-Shirts 25 €, hoodies 50 €, mugs 12 € (including tea and coffee flat)
  • Reservations: When registering as an attendee of this year's GPN you may already reserve T-Shirts which you can collect at the Merch Desk until Saturday, 2 PM.
    T-Shirts and hoodies that haven't been collected until Saturday, 2 PM are free to buy for everyone (as long as in stock).

Public transit tickets

This year there is no local transport ticket, as we assume that the Deutschlandticket is widely used by most GPN visitors and the local transport ticket would be very expensive for us.

Network / Wi-Fi

Pay the GPN22:NOC a visit.

Bring along

  • A DECT Phone! As usually, we will set up a DECT-system for Orga and Troll communication. more information: GPN22:DECT (we will not employ the eventphone-system!).
  • Network cables (3-5m): Most tables will be equipped with a switch that offers gigabit Internet connection. Please bring your own network cable.
  • Power Strips: remain a scarce commodity. Plese bring your own.
  • Server: are welcome. We have a lot of Internet access! 10GBit/s-ports for servers are limited but available. If you plan on using 2x SFP+ (either producer is fine for us) and -5m fiber, please organize it yourself. Finally, it is helpful if your servers provide a power-butten.
  • Lanyard: Visitor badges are overwhelmingly attached to a Lanyard. Who already owns one is herbey kindly invited to bring one, by doing so we save overall resources and don't take one lanyard per GPN back home. If you happen to have one or more to spare you can happily return them at the Info Desk. We will give them to other visitors.

Lodging, Food

  • Lodging: sleep-overs inside the building are not permitted. But you can find a place to sleep here. We listed hotels that are close to the spot and linked a find-a-bed.
    • Is there a nearby gym where we can sleep No.
  • Fryhstyck (breakfast): Will be cared fo on Friday, Saturday and Sunday. Depening on the total amount of rolls you eat, you may want to consider making a small donation.
  • Goulash: Rest assured, there will be goulash, once, at least. Please do note, the goulash will be vegan.
  • Soft ice machines, pizza ovens, waffle-o-mats, crêpes, popcorn, slushies etc.: Please contact organizers if you want to hack/play/distribute//give away/sell food. The sooner, the better.
  • Food delivery: of course, that is possible, too. --> Location.
  • Close-by food: here, is no list!


  • Volunteering always is a great idea. The event works because guests also help out as Trolls. Troll How-To explains what needs to be done. Don't forget about the Trollsystem.
  • Accessibility: The event is all on floor one / EG / ground level, toilets are also accessible. If you are concerned about overall accessibility, please get in touch with us. With your help we can eliminate possible barriers. More information on GPN22:accessibility.
  • Kids: Kids are most welcome at GPN, they are kindliest invited to get involved, depening on their experience they surely can join all the other hackers who are attending.
  • Pets: Based on past experiences we prefer for you not to pbring your pets to the event area. Exceptions can be made for assistance pets such as guide dogs.
  • Smoking: Smoking inside the building is strictly prohibited. Please do not smoke in or near the entrance areas. Smoking in the entrance areas is like peeing spots in a pool.
  • Longboards: As a consequence fof various accidents and an overall high risk of injuries (also for non-skaters) we don't allow skating on site (this also applies to hover- and skateboards, shortboards, cars, trains, seats, sofas, etc.).


  • Public: Contrasting other Chaos-Events the GPN is an open and public event. For example, both parts of the museum which is visited by many people on a daily basis, are connected and are right next to the Hackcenter. The visitors may be curious and ask what visitors are doing, we strongly encourage.
  • Photos: Visitors and employees of the building may be taking photos throughout the event. Please be aware of this. As long as those pictures are taken to reflect the atmosphere of the event we are okay with it, the same goes for time lapse videos. Even if there are recordings of fascinating projects by our visitors, as long as the object is the reason for the photo, not the person behind. We disapprove of close-up, portrait or group photos without consent. Though, neither can, nor do we legally want to prohibit these actions. Taking photos of attendees' screens is also not cool without consent.
