At the top of Brorfelde Bakke in the middle of Zealand sits Denmark's largest observatory. It was once a large workplace for astronomers at the University of Copenhagen, but today it has been transformed into an experience center.
With the view over Lammefjorden in a beautiful hilly landscape, the place is also a wonderful nature experience in itself.

… But start with this little appetizer of a video:



Since 2021, the Observatory has offered a completely unique form of accommodation on Zealand – namely their stargazing shelters. Now you can fall asleep to the sight of shooting stars and wake up to the sound of birds chirping. Nice!
It is architect, Kristoffer Tejlgaard, who is behind the four round stargazing heroes. Each shelter has room for 6-8 people, and the area can therefore accommodate up to 32 at once (ideal for groups such as school classes, etc.) - but can of course also bookes individually.
The curvature of the walls is designed so that you can sit up against the wall. During the day, an entire school class can receive instruction in a single shelter. When darkness falls, you can lie with your heads towards the center of the shelter, and enjoy the beautiful starry sky above you through a round glass roof.
To find the new shelters, guests must go through the Ice Age - a new geological activity area. From the paved main road, a handicap-friendly path runs through the Ice Age and on to the four shelters, so that both wheelchair users and prams can pass.
So take your family, friends or girlfriend under your arm and give each other a unique experience in the Zealand nature.
All year round, the science park offers a wealth of activities. Get an overview of some of them below:


From 1953 to 1996, the observatory was a living workplace for astronomers, students and craftsmen. Common to these was their passion for the sky. Driven by their curiosity, they stood night after night to gain a greater knowledge of the infinite and mysterious sky.
The world-renowned binocular construction had to turn the key in 1996, when the technologies used were digitized.
In 2016, you could open the doors again, and this time as a discovery center with a focus on astronomy, geology, technology and biology. Every day it becomes new discovery center explored by children and adults who are initiated into the mysteries of space.
In addition to the discovery center's eleven culturally protected buildings, the sky above Brorfelde is also protected. This means that there is no light to be found in the area after dark. Brorfelde is the only place in Denmark that has protected night darkness.
With a protected night darkness, the sky unfolds extra clearly, and under the correct weather conditions, you can see both the Milky Way and Mars with the naked eye!
