The Archenhold Observatory offers a wide-ranging programme for all ages: look through a telescope, listen to a talk or follow one of our thematic guided tours.
On the ground floor you will find our new exhibition “Astronomy is Observing and Measuring”, while temporary exhibitions highlight different subjects tracing the history of astronomy.
The “great refractor”, the longest lens-based telescope in the world, awaits you up on the roof. Other attractions of the Archenhold Observatory include the historic Einstein room, the small Zeiss
planetarium and a giant iron meteorite.
At an observatory you can use a telescope to observe the stars – but of course only when the skies are clear with no clouds to obscure your vision.
