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!

Travel, stay, and departure

  • We recommend you to only come to Dagstuhl if you are fully immunized against SARS-CoV-2. Before your trip to Dagstuhl, you should, by all means, conduct a Covid-(self-)test, and only travel if the result is negative.
  • At the moment, we are not required by law to check your immunization status. However, such a check could become mandatory again, even on short notice.
  • Each guest will find a a lateral flow Covid self-test in their room that they are required to use upon arrival (usually Sundays) before they have contact with other guests. In addition, all guests are required to take another rapid antigen SARS-CoV-2 self-test before breakfast on the third day of their event – housekeeping will deposit the test kits in the guest rooms.
  • Please observe the valid entry regulations of Germany. Further down you will find a summary of not constituting legal advice and links to important official sources. Any quarantine period that may be necessary upon entry cannot be spent at Schloss Dagstuhl (an isolation quarantine due to a positive test on site can be spent in Schloss Dagstuhl at cost price).
  • Please ensure a minimum distance of at least 1.5 meters to other people at all times.
  • A medical mask (CE tested: OP mask type II or IIR, FFP2, FFP3, N95 or KN95) is strongly recommended in all areas of the castle inside of buildings. Exceptions apply when eating and drinking or in your own room.
  • If you notice any symptoms as can occur with Covid-19, please immediately retire to your room and inform a member of Schloss Dagstuhl staff. Schloss Dagstuhl will then coordinate further action in close cooperation with the relevant authorities (an isolation quarantine due to a positive test on site can be spent in Schloss Dagstuhl at cost price). The symptoms can include fever, cough, shortness of breath, loss of sense of smell (anosmia), loss of sense of taste, inflammation of the nasal mucous membrane (rhinitis), sore throat, or general fatigue and tiredness [4]. For the omicron variant, instead of loss of tase and smell, loss of appetite and heavy sweating at night have been reported.
  • Should you require a PCR test or an official test certificate for the return trip, you will find the appropriate addresses below. Our staff at the reception desk will be happy to help you - please contact us as early as possible if you need assistance.

  • The use of some areas is restricted through limiting the number of people (e.g. lifts, toilets, fitness area).
  • Where necessary, use of more spacious rooms during coffee breaks (restaurant, library, exterior areas).
  • The seating capacities in the lecture halls are significantly reduced due to the distancing regulations. If needed, please contact Dagstuhl to see whether we can offer a video transmission solution between two rooms, or a Hybrid Meeting format including videoconferencing.


  • Excursions are generally possible, provided that the hygiene regulations are complied with. Our team will gladly inform you on site about the current regulations.

Test centers


Please note the regulations for entering Germany that are valid at the time of your trip. A summary of the regulations is provided by the German Foreign Office [1]. Schloss Dagstuhl cannot provide you with legally reliable information about these. However, please pay particular attention to the following (as of February 2, 2023):
  • If you come from an "area of variants of concern in which a variant of particular concern threatens to emerge" (As of February 2, 2023, this concerns only China) or have stayed there during the last 10 days before entry, you need a valid negative Antigen or PCR test (not older than 48h hours at entry).
  • If you come from an area with variants of concern (As of February 2, 2023, there are no areas with variants of concern) or have stayed there during the last 10 days before entry, you must register at before entering the country. Furthermore, you need a valid PCR test (not older than 48h hours at entry) and have to go into quarantine for 14 days. The quarantine does not apply if you are vaccinated against the variant with a vaccine approved for that variant by the RKI.

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. This concept was approved by the local health authority and in consultation with the local police authority. The company physician and the safety engineer have also been informed and have approved the concept. This safety concept is the basis for the above regulations.
