URBAUM is multiple ideas of a tree

a tree that is all trees 

in space and time

tall, grounded, ramified

a moment in life

an instant of perception

an imaginary tree

We invite you to climb up with us to the crown of our imaginary tree. Amid fictional branches, unreal leaves and fantastic birds you will discover music performances and surround soundscapes by Christopher Collings and Juan Verdaguer, in a landscape of digital imaging by Germán Greiner and art pieces by Hannah Montoux-Mie.  A unique experience from an unusual perspective.

In line with the current regulations in Germany we​ are required to check the following documents (either digitally or as a printout) when entering the Lichtturm:


  • Your ticket: Your ticket is personalised and is valid as a registration to the event.  You may also use the Corona-Warn app to register on-site if you wish to.

  • 3G rule: With a digital QR Code or through a certified printout, we need to verify one of the following:

    • your negative test result from the day of the event for an infection with the SARS-CoV-2 coronavirus (rapid antigen test or PCR test) 

    • or proof of complete Covid 19 vaccination with a vaccine approved by the European Union (the last vaccination must have been given at least 14 days ago) 

    • or proof of your recovery (positive PCR test result at least 28 days but no more than six months ago or, in the case of a more recent infection, in conjunction with at least one vaccination against Covid-19).

  • Your photo ID


Due to capacity limitations the Lichtturm allows no more than 18 seated guests for each performance and 30 guests at any given time during the installation.​


The installation and performances at Lichtturm involve climbing up four floors through helical staircases. Unfortunately the Lichtturm does not count with an elevator and it is not accessible for wheelchairs. To account for this, a video of the performance will be made available in the future.


It is possible to park your car in the surroundings of the Lichtturm.

Parking is free in the area.
