A trail of light and sound artworks has opened in Vienna's Schwarzenberggarten, the garden beside Belvedere Palace, in the first Vienna edition of Klanglicht, an event previously staged in Graz since 2015. Titled Klanglicht im Park: The Sound of Light, it runs from October 23, 2026, to January 10, 2027, open Monday to Saturday from 1 p.m. to 7 p.m.

The route crosses the garden's four terraces, leading visitors past works by Austrian and international artists. Its centrepiece is British artist Luke Jerram's Museum of the Moon, a seven-metre-wide illuminated sphere that reproduces the moon's craters and mountains from NASA imagery. Architect Katja Paternoster contributes small wire figures of domestic and wild animals, made to draw attention to creatures that often go unnoticed in cities.

Other stops include Flora, an interactive sculpture by Philipp Artus that visitors can control with a touchpad, and Nature Art by Bart Ensing, which stretches wires between a tree and the ground. The trail ends with Terre Roulante, or Rolling Earth, a round neon work by Vienna artist Miriam Hamann inspired by an astronomical drawing. An audio guide narrated by Hilde Dalik accompanies the walk, and the event is curated by Birgit Lill-Schnabl, who also curates the Graz edition.

Organisers present the garden trail as a retreat in the middle of the city, pairing an evening stroll with large-scale public art. For Vienna, the debut extends the Belvedere's surroundings beyond its galleries and into the open air, giving the autumn season a free-to-wander attraction that runs through the darkest weeks of the year.
