Winter Light Bar

Experience the top of the Round Tower like never before, as the platform transforms into a glowing winter bar!

The view from the Round Tower’s platform is truly unique, even in winter. For centuries, astronomers and visitors from around the world have looked up toward the sky and the shining stars, while taking in the lights of the city of Copenhagen.

In February, the Round Tower turns up the light, as the platform becomes a radiant winter bar. There will be music and a bar that will offer beer and bubbles, as well as drinks such as “Light and Stormy” or “Glow & Tonic.” Enjoy your drink while exploring Yoke’s light installation “While the Light Hesitates” at the top, inspired by Ole Rømer’s discovery of the delay of light.

We recommend that guests bring extra warm clothing and dance to keep warm, but if that isn’t quite enough, blankets will be available to borrow.

The Library Hall will also be open. Here, you can experience the newly opened exhibition Ad Lucem, as well as the Round Tower’s historical exhibition about Ole Rømer and his discovery of the hesitation of light.

Access to the winter bar is included in the regular admission, but be aware that if interest is very high, queues may form, as the Viewing Platform allows a limited number of visitors at a time.

The event is part of the program for LIGHTYEAR 2026 at the Round Tower — a full year in which we celebrate light and the 350th anniversary of Ole Rømer’s groundbreaking discovery of the speed of light.
