Directions and visits to GEO600

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

Please note that due to the Covid-19 pandemic, it is currently not possible to visit GEO600 until further notice.

Visiting GEO600

Visit to the GEO600 central building during the Open Day 2018.

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 viewing appointment for you within our regular working hours. The tour lasts around 90 minutes and includes an introduction to gravitational waves and the astronomy they allow, as well as a detailed tour of the institute grounds and the technology of a gravitational wave detector.

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

Individuals can occasionally join such group tours. Please contact  if this applies to you.

An open day is held once a year on a weekend day in summer. On this day, the detector site can be visited without prior notice.
