SARS-CoV-2 prevention measures

Schloss Dagstuhl wants all guests to feel as comfortable and safe as possible during their stay. In the following, we list our most important rules and some of the measures we have introduced for your protection. We ask for your understanding that changes in current legal regulations or changes in travel regulations may, under certain circumstances, result in modified measures and rules for our institute and our guests at short notice. In general, we ask all guests to decide responsibly about seminar participation or cancellation.


Please pay attention to the information for your travel and stay listed below!

    • have been fully immunized with EU-approved vaccines [3] (i.e., are fully vaccinated), or

    • had a positive COVID-19 PCR-Test at least 28 days ago, but not more than 90 days ago [5] (i.e., count as "recovered"),
    and present the corresponding (if possible digital (for EU), otherwise the official paper) proof at check-in, you can come to Dagstuhl. In addition, an official piece of identification (original) has to be presented. (If you use the self-service check-in, please present these documents at the reception first thing the next morning, before breakfast or seminar participation.)
    Before your trip to Dagstuhl, you should, by all means, conduct a Covid-(self-)test, and only travel if the result is negative.
  • The proofs mentioned in the point above (valid vaccination certificate and, if applicable, proof of overcome infection) must also be uploaded to us before the seminar in a timely manner. Details will be sent to you in time by email (e.g. together with the voucher). About one workday after the upload, you can check at DOOR whether the uploaded proof was successfully verified. Of course, we delete these uploaded certificates shortly after the seminar.
  • On the pillow in their guest room, all guests will find a lateral flow Covid self test that they should use upon arrival (usually Sundays) before they have contact with other guests. In addition, all guests are required to take a supervised lateral flow self test for SARS-CoV-2 on the first day of their event (usually Mondays) and 2 days before the end of the event (usually Wednesdays). The tests are provided by Schloss Dagstuhl. Please also pay attention to the notices at the reception desk.
  • The local health authority requires us to record your private email address and your private mobile phone number upon your arrival. We have laid out the requisite paper forms, which you can fill out and deposit securely in a "letter box". In case of a confirmed infection in your sphere, these forms will be forwarded to the local health authority to enable them to contact you and trace the infection. The data will not be recorded electronically and will be destroyed after 4 weeks.

Hygiene concept

A protection and hygiene concept for Schloss Dagstuhl was developed on the basis of a hazard assessment, including risk evaluation, based on the currently applicable Saarland state ordinance and the recommendations of the RKI.
