Visiting the Great Refractor
The "Science Park Albert Einstein" on Potsdam's Telegrafenberg (see locations) is home to the Great Refractor and the Solar Observatory Einstein Tower, which are very interesting in a history of science context and still very popular with all age groups. The park is open during the day, all buildings can be visited from the outside without making an appointment. Guests of the science park only need to register at the park entrance (front gate).
The Great Refractor can be visited within a guided tour from the inside. Dates and hours are announced via our public events page and via the local media in Potsdam; guided tours for groups of 15 or more people are also possible via the Förderverein Großer Refraktor e.V..
