After sunset, Prague is preparing to become something other than the city visitors know by day. Its medieval façades, public squares and historic streets will become screens, stages and canvases as light and digital art reshape the Czech capital this autumn.
The transformation will come with the 14th edition of the Signal Festival, running from October 15 to 18 under the theme “Dream On! Dreams and Visions.” Twenty-one installations will spread across Prague, with the festival expanding into the Dejvice district for the first time.
Signal belongs to a growing cultural movement in which technology is no longer simply a tool for making art, but part of the artwork itself. Projections, interactive installations, sound and light will intersect with Prague’s historic architecture, creating temporary worlds that exist only for a few nights.
Among the most striking works is expected to be “Living in Truth” at the Old Town Hall by Ukrainian artist Svitlana Reinish. Inspired by Václav Havel’s The Power of the Powerless, the projection will transform the historic building with words connected to truth, freedom, justice, love and democracy before gradually distorting and disappearing.
The choice of setting is significant. Prague has long carried the weight of its political and cultural history in its architecture. By projecting contemporary ideas onto those surfaces, the festival creates a conversation between the city it was and the city it is becoming.
The new Dejvice route pushes that conversation beyond Prague’s historic centre. Students, artists and technology specialists will contribute interactive works, audiovisual projects and experiments that bring contemporary creativity into everyday public spaces.
There is something inherently theatrical about the festival. A building that has stood for centuries can suddenly move. A familiar street can become an immersive artwork. A public square can become a place where thousands of strangers stop, look upward and experience the same fleeting image.
That impermanence is part of the attraction. Nothing is being permanently added to Prague’s skyline; instead, the city itself becomes the medium.
For four autumn nights, Prague will ask its visitors to see the familiar through unfamiliar eyes and to imagine what happens when one of Europe’s historic capitals begins to dream in light.
