Directions and visits to GEO600

The gravitational-wave detector GEO600 is situated 20 kilometers south of Hannover close to Sarstedt near the village Ruthe.

Visiting GEO600

Please note that the detector site can only be visited after previous date arrangements. If you would like to get a tour of the GEO600 facilities, please contact  to coordinate the details of your visit.

For groups of seven or more, we will arrange a visit for you within our regular working hours. The tour takes about 90 minutes and includes an introduction to gravitational waves and the astronomy they allow, as well as a detailed tour of the site and the technology of a gravitational-wave detector. Tours are offered in English as well, just ask.

To visit the central laboratory building, an age of 16 years is required due to laser safety regulations.
