From October 16-19th in Prague, Signal Festival, one of the largest showcases of digital and creative culture in Europe, returns to illuminate the Czech capital’s historic cityscape with digital and light-based art.

For its 13th annual edition, Signal Festival 2025 has secured some near-legendary pieces for its estimated half a million attendees, including Bill Viola‘s video installation Tristan’s Ascension, which will appear at the National Gallery Prague- Convent of St Agnes of Bohemia.

The festival transforms the Prague into a living canvas and a platform for discovery and enlightenment – one where cutting-edge technology and contemporary art confront the world’s most pressing challenges Against this backdrop, the Signal Festival 2025 edition sets the stage for contemporary technology-driven digital and light art to be perceived as a paradox: technology infused with emotion. Precision is paired with intuition, algorithms with ephemerality, and logic with randomness. 

As the final chapter in the Ecosystems trilogy (2023–2025), this year’s theme —Solutions—proposes that the key to navigating global crises and unlocking global unity lies in our ability to perceive the world as an interconnected whole. In this context, artists examine how ecosystems, both natural and digital, function, collapse, regenerate and evolve.

One of the highlights of this year’s festival, Moravian Amazon by Co-Vision encapsulates this theme. A large-scale multimedia artwork, it explores the heritage of the Moravian Amazon, Europe’s largest rainforest. Co-Vision is made up of collaborators from across Central and Eastern Europe (Czech, Slovak and Ukrainian artists Marie Tucková, Katarina Gryvul, David Prílucík, and the artist duo Selmeci Kocka Jusko), emphasising the importance of trans-national unity in offering up solutions to global problems. The piece itself seeks to raise awareness of the ecological importance and vulnerability of this unique landscape.

Signal Festival 2025 takes place across Prague and incorporates two main routes. One route takes in the heart of Prague, with its Gothic and Baroque landmarks, while the other crosses the Vinohrady district, with its Art Deco and neo-Gothic architecture. The intention? To simultaneously celebrate the past, present, and future.

Ten installations will be freely accessible, with additional programming (known as Signal INSIDE) available as ticketed events which offer an intimate atmosphere in stunning indoor locations. This year also marks the opening of Signal Space, a new permanent gallery for digital art, in Prague’s Neo-Renaissance Market Hall.

“Each year, Signal Festival is an opportunity for us to showcase digital art from a new perspective. This year, for the first time, we will present a 3D light projection on a 10 x 20 meter waterscreen. The image is projected onto a screen made of water mist, so the projection appears to float in the air. The effect resembles a hologram and creates a truly magical atmosphere above the river.”

Martin Pošta, Signal Festival CEO and Founder
