Protective and hygienic measures

The Museum Koenig follows the requirements of the Corona Protection Ordinance of the State of North Rhine-Westphalia (link is external).

Accordingly, the following applies to you:

  •  Obligation to wear a medical mask
  • Maintain a minimum distance of 1.5 m from other people

If you feel ill, please stay at home.

Use the facilities for hand disinfection.

Cough or sneeze (along with the mask) into the crook of your arm and keep your hands away from your face (eyes, nose, mouth).

Avoid forming groups that are too close together.

In order to further minimize visitor encounters, the exhibitions can currently only be seen as a tour.
