Signal Festival, the Czech Republic’s premier platform for digital and creative culture, returns to Prague from 16-19 October 2025 for its 13th edition.
The festival, renowned for transforming urban spaces, will this year debut a major highlight in its programme: large-scale video mapping projected onto the historic Old Town Hall tower. As one of the most visited cultural events in the country, the festival consistently attracts hundreds of thousands of visitors annually and plays a significant role in redefining the city’s cultural tourism offer through creative technology. In a major first for the event, the nearly 70-metre-high tower of the Old Town Hall will be transformed into a projection canvas. Italian creative studio MammasONica will present OVERLOЯD, a digital artwork designed to explore the emotional relationship between data and architecture. For the first time at the festival, laser elements will be incorporated into the mapping, expanding the sensory scope of the installation and further blurring the line between physical structure and digital narrative. By activating outdoor and indoor city spaces, the festival creates a city-wide platform for creative placemaking, making it a notable model for cultural programming that merges public realm activation with high-level digital artistry. Signal Festival’s growing prominence highlights the increasing demand for large-scale, immersive digital experiences within urban cultural calendars. For B2B stakeholders, including projection specialists, creative studios, cultural programmers and urban planners, the 2025 edition offers insight into how heritage buildings can be transformed through temporary digital interventions. The success of installations like OVERLOЯD and ITERACE points to an emerging convergence between digital storytelling and architectural interpretation, opening up new opportunities for collaborations across tourism, event production and media art. Signal Festival contributes to a broader discourse on the future of experiential culture in heritage cities by continuously pushing the boundaries of how digital content interacts with historical sites.
