Planet Workshop for Kids
Color the planets and create your own Solar System when the Round Tower invites you to join a creative drop-in workshops for children and their adults.
Create unique and imaginative celestial bodies! Armed with scissors, glue, cotton balls and crayons, only imagination sets the limits.
The Round Tower provides tools and drawing kits, but you decide the patterns and colors of your celestial creations.
The workshop is open to all who have paid regular admission, though spaces are limited.
The event is part of the program for Round Tower’s astro festival “KOSMOS”.


Drop-In Workshop: Create Your Own Scenography
With inspiration from the current exhibition “The Tryouts” and theater painter Carl Lund, who had his painting workshop in the Library Hall in the early 1900s, we will create our own miniature stage designs in this workshop!
Test your skills as a theater painter as we use various forms of cardboard, paper, paint, and cutouts to craft our own alternative worlds, where new interpretations of reality can unfold. What story would you like to tell, and which characters or figures will be part of it?
The workshop is led by Simone Syska Andersen, a creative consultant, art communicator, and educator with several years of experience in the museum world.
Participation is free with the regular admission to the tower, but seats are limited. If the workshop is full, we recommend taking a stroll through the exhibition, which is also included in your ticket, to gather inspiration, and coming back afterwards.

Astro Evenings for Families
Join us during selected days in the autumn break for Astro Evenings for children and their adults, with special evening openings for families at the Observatory and a creative planet workshop.
Visit the Observatory
Remember to wear warm clothes when we open the Observatory especially for families and focus the telescope lens on Saturn or the Moon, weather permitting. There is limited space in the Observatory at any one time, so don’t forget to visit the planet workshop in the Reading Room, where you can create your own celestial bodies. You can also buy a cup of hot cocoa or other refreshments for children in the Library Hall.
Planet Workshop
Color the planets and create your own solar system when the Round Tower invites children and adults to a creative drop-in workshop. Try your hand at scissors, glue, cotton balls, and beautiful wax crayons that can be blended with water.
The Round Tower provides colors, tools, and drawing kits, but you decide the patterns and colors of the celestial bodies!
Note: The Round Tower cannot guarantee that we will be able to see celestial objects through the telescope if the weather does not allow it! However, if the weather doesn’t cooperate, we will still keep the Observatory open, and our astronomers will instead share more about the Observatory and the large refractor telescope, which can magnify 80-450 times.
Tickets include regular entry but must be booked in advance.

Drop-in family workshop: Make corals out of clay
Join a creative underwater journey with clay and organic forms when ceramic artist Anne Mette Edeltoft invites you to an inspiring family workshop in connection with the exhibition “Being Coral”.
The exhibition gives us an intimate, sensory insight into the planet’s beautiful but endangered coral animals. Under guidance from artist Anne Mette Edeltoft, you will learn simple techniques for shaping and modeling as you create your own interpretations of these fascinating creatures in self-hardening clay.
The workshop is open to everyone who has paid general admission, but spaces are limited. If the workshop is full, we recommend taking a tour of the exhibition for inspiration first.
During the workshop, you’ll also have the opportunity to closely examine real coral skeletons and make casts of different skeletal structures.
Anne Mette Edeltoft works with ceramic sculptures and is particularly fascinated by corals and their organic colors and patterns.

Autumn Holiday: Science and Other Stellar Experiences
Autumn Break is filled with curiosity at Christian IV’s Historic Observatory Tower. Dive into creative planet workshops for kids, experience the magic of the Observatory at the top of the tower, and explore the science exhibition “From Science to Society.”
Planet Workshops for Kids
October 14th–18th, 10-16

Color the planets and create your own Solar System when the Round Tower invites you to join creative drop-in workshops for children and adults. Try your hand at scissors, glue, cotton balls, and beautiful wax crayons that can be blended with water to create colorful planets.
The Round Tower provides tools and drawing kits but you get to decide the look and design of the celestial bodies.
The workshop is open to everyone with a regular entrance ticket, but there are limited spots available.
Astro Evenings for Families
October 14th & 17th, 18-21

Join us when we open the Observatory exclusively for children and their adults and adjust the telescope to see Saturn or the Moon if the weather permits. During the evening you can also make planets in our open planet workshop in the Reading Room next to the Library Hall or solve fun astronaut challenges in the Spiral Ramp.
Remember to dress warmly for the Observatory!
Registration is required for Astro Evenings.
Exhibition: From Science to Society
Every day until October 20th

Learn more about both famous and unknown scientists together in the Round Tower’s Library Hall, where you can currently explore the exhibition “From Science to Society,” presented in collaboration with the Society for the Dissemination of Natural Science (SNU).
From Monday to Thursday in week during Autumn Break, there will be “Mirror Image Days” in the exhibition, where you can delve into the chemistry behind life’s twists and turns! The building blocks of nature exist as mirror images – something called ‘chirality’. You may have never heard of it before, but once you become aware of chirality, you’ll see it everywhere: your hands, your shoes, you name it – even the Round Tower is chiral!
At the experiment tables in the exhibition, you will be able to smell and taste mirror image molecules and learn more about chirality. Build the organic molecules you taste and discover why they are called ‘mirror image forms’.

Ole Rømer Challenge: Test Yourself in the Spiral Ramp
It can be hard work going up and down the Spiral Ramp! How many times can you make the trip? Join the Ole Rømer Challenge during the Golden Days Festival and test your strength in the spirit of Ole Rømer.
Even if you search far and wide, it’s hard to find anyone who has had as many exciting jobs as the astronomer Ole Rømer. He didn’t just work as the director of the Observatory at the top of the Round Tower—he also served as Chief of Police, Mayor, Fire Chief, School Principal, Supreme Court Judge, and much more!
But Rømer didn’t do it all himself. He needed others to pitch in too, which led him to wonder how much work a person could actually handle in a day. To find out, he conducted an experiment in the Round Tower in 1690. He asked two strong, young soldiers to walk up and down the Spiral Ramp—over and over again—until they couldn’t continue. They managed 60 trips in four and a half hours, and Rømer thought that was quite impressive.

Take on the challenge
As part of this year’s Golden Days Festival, which focuses on the theme of work, visiting children can take on the challenge and test their own endurance on the Spiral Ramp! Which path will you choose? The outer path with a 10 percent incline? Or the inner path, which is even steeper with a 33 percent incline?
Don’t worry—you don’t have to go as many times as Ole Rømer’s soldiers. In our mini-experiment, you just need to see how many trips you can complete up and down in four and a half minutes. Remember, one trip only counts when you’ve gone both up and down. You’ll find the starting point near one of the windows in the Spiral Ramp—so keep an eye out!
Win a season pass
When you’re done, take a picture of yourself and the Spiral Ramp and post it on Instagram. Be sure to mention how many trips you completed and use the hashtag #oleromerchallenge.
By doing so, you’ll enter a competition to win a season pass to the Round Tower for you and your family. That way, you can come back and tackle the Spiral Ramp as often as you like!
This event is part of the Round Tower’s program for Golden Days Festival.

Become the King’s Postman
During the summer holidays, children can enter the service of Christian IV and learn much more about the king on the occasion of the 400th anniversary of the Danish postal service.
The Round Tower was erected by King Christian IV, who built its round walls in the royal colours of yellow and red. The same colours were used for many years by the Danish postal service.
This is no coincidence since it was Christian IV who founded the postal service when issuing a decree on postmen on 24 December 1624.
On the occasion of the 400th anniversary, you can become a postman in the Round Tower for the summer holidays. At the entrance you can take a letter which you will be able to fill in with letters as you find the yellow and red bubbles throughout the tower.
By means of the bubbles, you can find the secret word but also learn much more about Christian IV and his connection with the Round Tower. The summer holidays activity for children is free when you have paid the entrance to the tower.
Design Your own Stamp at ENIGMA Museum
When you have found the secret word, you can take your letter to ENIGMA – Museum of Communication, which is located Øster Allé 3 in Copenhagen.
If you bring the letter with the secret word, you get free access to ENIGMA for all children up to the age of 18 until 29 September 2024. Children under the age of 10 must be accompanied by min. 1 paying adult.
At ENIGMA you can experience the story of Christian IV organising the Danish communication and many other stories. You can also design and have your very own stamp printed to take home – free of charge.
