Valentine’s Day with Star Gazing and Sweet Music

Bring your date on a unique Copenhagen date this Valentine’s. Gaze at the stars from the telescope in our Observatory and enjoy some sweet music in the Spiral Ramp when Danish DJ Mads Axelsen sets the vibe for a lovely evening.

Invite your date, spouse, lover or best friend for a different Valentine’s date experience this February. Stroll up the Round Tower’s Spiral Ramp where Copenhagen-based DJ and radio host Mads Axelsen turns up the volume with a warm, eclectic DJ-set of love songs perfect for enjoying the evening with that special someone.

Enjoy the music, get a little drink from our pop-up bar or rest for a while on the Kissing Bench near the tower’s top before heading for the stars in the Observatory, where the our astronomers will adjust the telescope and guide you through the night sky.

End your night on the Viewing Platform at the top for a stunning panoramic vista of Copenhagen or go down to the Library Hall and take a peek into the floral fantasy that is our current exhibition.

Access to music, stargazing and the exhibition are all included in your entry ticket.

Please note! The Round Tower cannot control the weather or the sky’s visibility. In case it is overcast this night and the stars are out of sight, our Observatory will remain open for a visit and you can still enjoy the tower’s ambience and the beautiful view of Copenhagen by night.

UngKlang: Christmas Concert

Join us for a magical Christmas concert when four choir singers from the vocal ensemble UngKlang performs in The Spiral Ramp on December 13th. Afterwards, our Observatory is open for stargazing.

Experience the heavenly acoustics of our iconic tower as the choir wanders up through The Spiral Ramp and let their voices fill the space with classical Danish Christmas carols and psalms.

Afterwards, our Observatory is open for stargazing from 6PM – 9PM. Climb the final steps to the very top of The Round Tower where our astronomers will be ready to guide you and you can look into our telescope yourself.

Entrance to the concert and the Observatory is included in your entry fee. Come early and bring warm clothes for the Observatory.

Debate: Organizing Architecture

Works+Words and Magasin for Bygningskunst og Kultur presents the debate Organizing Architecture in relation to the current architecture biennale in The Round Tower. The talk will be held in English

This evening, architecture is viewed as a professional field with an organizational infrastructure, theories, discourses, interests and power structures. A field in continuous transformation through the influence of multifarious actions, events, and initiatives. Two such initiatives, respectively Works+Words 2022 Biennale in Artistic Research in Architecture (W+W 22) and Magasin for Bygningskunst og Kultur Nr. 4: Faglig organisering (MBK 4), join forces for a discussion on incentives and strategies to impact architecture. 

The event plays out as an open discussion between contributors from Works+Words 2022 and Magasin for Bygningskunst og Kultur 4 and welcome participation from other attendees. The focal point is how architecture transforms through the organization of events and production of works. The discussion will be opened by editor for MBK Morten Birk Jørgensen and curator of W+W 22 Peter Bertram. 

Attending contributors include among others: 

Peter Bertram, Kgl. Akademi 
Initiator and curator of W+W 22 

Christine Bjerke, Building Diversity 
Contributor to MBK 04, ROOM TO BE, ROOM TO ACT

Yuxiang Li, Kgl. Akademi

Culture Night 2022

Experience the Round Tower at Culture Night in Copenhagen, where we offer a special programme.

The night of culture since 1993
More than 250 museums, theatres, libraries, churches, ministries, parks and squares all over the city welcome the public during Copenhagen’s biggest annual one-day event – and the many exciting events show that the city embraces a wide range when it shows its many sides of cultural life.
For over 27 years, Culture Night has been one of Copenhagen’s most organized and well-attended cultural events. When the schools go on autumn break, the Kulturnatten association creates a festive evening where the entire city’s cultural life merges and opens up to joy and inspiration for all of us.
Program in Rundetaarn:
18.00 Admission with Kulturpass. The observatory is staffed and the exhibition “when the world becomes our body” can be seen in the Library Hall. In the exhibition, the artists Benjamin Skop and Amund Bentsen will be present and there is a special programme.

SPACE Science Festival

Rundetaarn marks Science Year22 with three weeks in space, where cosmos, light and sound occupy the tower’s Library Hall. RUM Science Festival first offers a journey of discovery to our cosmic neighbor planet Mars and then the space in the Library Hall is transformed by the work of art Contra. Through a series of talks, exhibition and music, the space between art and science is explored.

Rundetaarn was built as an astronomical observatory and has been the center of science for centuries. Art has since taken the place of books in the Library Hall, while stars and planets are still viewed from the top of the tower.

Our cosmic neighbor

The planet Mars is the center of the first part of the science festival. In collaboration with astrophysicist Tina Ibsen, a mini exhibition is shown about our cosmic neighbor, which in these years is the subject of major research projects and hides secrets that science is trying to uncover.

Pure photon energy in art

A scene change takes the audience from the journey to Mars back to the space in the Library Hall, where art meets science in the light installation Contra. The work was created by the artist collective Vertigo and consists of pure photon energy, i.e., the small energy packets of electromagnetic radiation that light consists of. Created out of light and smoke, a changing, architectural object emerges in the room, which the audience can both view from the outside and step into. The physical form in Contra is two triangles that stop the light so that the figure’s shapes and colors stand out clearly. Along the way, Vertigo talks about the technique behind and how they created Contra.

Walk the planet path

Finally, a special challenge awaits the tower’s smallest guests. Children are welcome to run, jump or how about walking backwards on the curvy planet path up along Rundetaarn’s spiral ramp, which is divided at points into distances, exactly corresponding to the solar system on a very small scale. The seven planets are illustrated and explained along the way to the top.

Cancelled: World Voice Day

The World Voice Day was established on April 16th in 1999 with the main goals of increasing public awareness of the importance of the voice and alertness to voice problems.

In Denmark, professionals from different associations established a work group in 2005, dedicated to arrange events to mark the World Voice Day.

In 2020, Saturday September 19th the Round Tower will be full of events to celebrate the voice and all is included in normal entry.

How do we return to the Moon?

Debate event in the Round Tower Library Hall, feat. the Danish astronaut Andreas Mogensen, John Horack (Neil Armstrong Chair in Aerospace Policy, The Ohio State University),  Emily Law (NASA JPL).

How can we return to the Moon? This is being discussed around the globe by national space agencies. Will it happen in cooperation or in competition, and how can Man even live in space? What have we learned from the Apollo Mission and what holds the future?

The panel debate is part of Space Days 2019, focusing on the Moon. The exhibition arranged by the Danish Astronautical Society “Around the Moon” is also open during the event.

Organizer: Danish Astronautical Society in collaboration with IDA Space and Rundetaarn. Andreas Mogensen’s participation is made possible in collabotation with ESA and Ministry of Higher Education and Science.
