Star Gazing from Above

Join our amateur astronomers for a night of star 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 the normal entrance ticket.

Used by the University of Copenhagen until 1861, the Round Tower is Europe’s oldest functioning observatory. It is now regularly used by amateur astronomers and open to the public all year round.

On top of the Round Tower there has been several different observatory buildings. The latest one dates from 1929. The Observatory is 6.75 metres high and 6 metres in diameter and contains a refracting telescope with 80–450 x magnification.
