Drop in-proposal at The Round Tower

Are you planning to get down on one knee before the love of your life? Why not do it with Copenhagen’s most charming view as the backdrop for your unforgettable moment of love?

In celebration of the Golden Days Festival, Rundetaarn is turning up the romance and exclusively inviting you to drop-in proposals outside regular opening hours. For the very first time in Rundetaarn’s history, you can ask your beloved the big question in the historic and romantic setting of Rundetaarn — completely undisturbed by tourists or other guests.

It’s free, and you can book a time slot between 8:00–9:00, 9:00–10:00, or 20:00–21:00 during the period from September 5th to 21st.

This event is part of the Golden Days Festival (September 5–21). The theme is ‘Love’, which you will also be able to feel at the Round Tower. Follow September’s love events right here.

Astro Bar in September – Fall sunset and drinks with a view

Explore the art exhibition and enjoy a 360-degree sunset over Copenhagen with drinks and music, as the Round Tower stays open late and transforms its rooftop into a cozy Thursday bar.

Take a leisurely walk up the Spiral Ramp hand in hand with your sweetheart or best friend, make a stop halfway in the Library Hall to explore the current special exhibition, and finish your visit on top of the Round Tower with drinks, music, and a summer sunset.

On September 18th, the tower will stay open late in both the exhibition hall and on the rooftop, as we swap souvenirs and ice cream in the rooftop kiosk for beers and cocktails and invite you to Astro bar – the city’s most scenic bar with an unbeatable view.

This means that with a single ticket, you can explore the exhibition in the Library Hall, get help from astronomers to look through the telescope in the Observatory, and enjoy the last rays of sunshine setting over the city from the viewing platform on top.

Please note: Tickets are sold in advance due to limited space, but it is also possible to buy a ticket at the door if capacity allows.

If the weather doesn’t allow for an open-air event, we’ll move the festivities inside the Round Tower.

A beacon of light – Concert with Di Garbi

The Round Tower is transformed into a beacon of light, prayer and compassion, as we join Danish composer and pianist Di Garbi on a pilgrimage through the tower and gather for a concert in the final hours of the sun.

The audience is invited to a special evening where music and song will spread universal love – for each other and for the planet. The empty Library Hall in the Round Tower will set the scene for the concert, where Di Garbi, with her classical roots and poetic musical language, will perform beautiful compositions on the grand piano placed at the center of the space.
Di Garbi has a special focus on historical spaces from a time when architecture imposed different demands on sound.

The audience can enjoy this unique, almost ritual-like, experience seated on chairs and cushions around the piano in the historic hall at the heart of the Round Tower. A sense of unity and togetherness will arise as Di Garbi invites everyone to sing along to various mantras – both around the piano and in the Spiral Ramp.

After the concert, guests will have the opportunity to walk up and enjoy the view over Copenhagen – and perhaps catch a glimpse of the day’s last light.

Composer and pianist Di Garbi

Multi-artist Di Garbi

As a composer, singer, lyricist, and pianist, Di Garbi is a versatile musician who transforms historical spaces into the most enchanting concert halls through melodic music of classical, electronic, and cinematic character. Her compositions explore the human mind in a poetic musical language, often with a calming effect on the listener’s nervous system. In 2024, Di Garbi became the first Danish solo artist ever to record an album at Abbey Road’s Angel Studio in London.

Previously, Di Garbi has performed as artist-in-residence at venues such as Thorvaldsens Museum, the Royal Chapel at Christiansborg Palace, and Aarhus Theatre. Now, audiences can immerse themselves in her musical universe here in the Round Tower. We look forward to welcoming you.

We meet at the entrance to the tower and embark together on a shared pilgrimage to the Library Hall. Doors open half an hour before the concert begins.

A special thanks

Di Garbi are joined by three special guests:
Cæcilie Balling, violinist
Bilal Irshed, oudist
Stine Ciconia Rejnholdt, reading and text

The artistic team behind the concert also includes:
Marie Nørgaard Nielsen, costume designer
Glenn Rottland, MOTU, sound and setup
Stine Ciconia Rejnholdt, production assistant
