Look Through the Telescope

Join our astronomers for a night of star and planet gazing. During the winter months the Observatory is open and manned every Tuesday and Wednesday evening from 18 to 21. No reservation is needed – the visit is included in your entrance ticket.

Used by the University of Copenhagen until 1861, the Round Tower hosts Europe’s oldest functioning observatory at the top. Today, it is open to peek inside year-round and manned on special days by the Round Tower’s astronomers who invite our guests inside to take a look through the refracting telescope with 80-450 x magnification. The season of stargazing takes place from October to March.

Please Note: Stargazing is not possible if the sky is overcast.
The Round Tower cannot guarantee visible stars or planets if the weather does not permit.

If it is cloudy or overcast, our astronomers will still keep the Observatory open for visits and will in stead tell you more about the telescope and the old Observatory.

What is visible on the night sky?

As mentioned above, the Round Tower cannot guarantee clear skies and perfect visibility for stars and planets if the weather does not permit, but here you can see the prognosis for which stars or planets our astronomers will be looking for the next couple of months:
