Signal Festival Illuminates Prague’s Landmarks with Digital Magic
In its fourteenth year, Signal Festival brings a mesmerizing blend of art and technology to Prague’s streets and buildings. The event, founded by Martin Pošta and his team, transforms the Czech capital into a canvas of light and sound, captivating locals and visitors alike. Known for its innovative projection mapping, the festival creates immersive experiences that redefine public spaces.

The Origins of Prague Signal Festival: From Film to Light Art
Martin Pošta’s journey into digital art began long before the inception of Signal Festival. With a background in filmmaking and documentary production, Pošta’s trajectory changed when a meeting friends in a bar sparked the idea of using projection mapping on a local church. The project evolved to feature a spectacular display on the Prague Astronomical Clock for its 600th anniversary, drawing widespread admiration and laying the groundwork for the renowned event, now a globally recognized celebration of art and light.

Building a Global Platform for Light Artists
Since its debut, this festival has grown to include a permanent venue, Signal Space, in the heart of Prague. This space serves as a hub for ongoing digital installations and community engagement. The event attracts artists from all over the world, enabling them to contribute site-specific works that resonate with the city’s historic and cultural fabric, making it a premier light art festival.

Each year, they bring together talented individuals who share a passion for pushing artistic boundaries, resulting in ephemeral yet impactful installations that infuse the event with vibrant energy.

Laterna Magika: A Fusion of Art and Performance
A highlight of the festival is the reappearance of Laterna Magika, a distinguished group under the Czech National Theater. Known for their innovative use of light and performance, they employ a unique technique that highlights only illuminated parts, crafting illusions that enchant audiences. This year, their work draws inspiration from a Czech poem, presented at the Old Wastewater Treatment Plant in Bubeneč during the dazzling celebration.
