The Signal Festival is a festival of light, videomapping and light installations, and belongs to one of the greatest cultural events in the Czech Republic. Under the direction of Czech and international experts in light design in artistic spaces, Prague’s streets and public areas, its most popular historical monuments as well as lesser known corners, all change over the course of four evenings to capture the different facades of today’s and yesterday’s Prague in non-traditional ways.

For four autumn nights, Prague will transform into a glowing open-air gallery, where historic architecture meets cutting-edge digital art in a breathtaking celebration of creativity.

Signal Festival 2026: New Route, New Artists and New Experiences

The 14th edition of Signal Festival will take place from 15 to 18 October 2026. This year’s theme, Dream On! Dreams and Visions, explores the boundaries between reality, imagination and new technologies. The festival will feature 21 installations across two routes – in Prague’s city centre and, for the first time, in Dejvice.

The new Dejvice route is one of the main highlights of this year’s festival. Visitors can see Taiwanese artist Aka Chang’s ten-metre-high laser installation Multimmersion_Upside Down on the Vltava, while American digital-art pioneer Jim Campbell will present Scattered Light, a monumental installation made up of 1,500 LED lights. The route also introduces Student Visions, a new section showcasing creative projects by students of Czech Technical University in Prague and the University of Chemistry and Technology, Prague.

The festival’s international programme will also feature works by artists including Laurie Anderson and Hsin-Chien Huang, whose immersive work To the Moon invites visitors on a journey inspired by science, mythology and science fiction, and Austrian artist Kurt Hentschläger, whose FLUX creates an intense experience of light and darkness. German artist Felix Frank will transform the façade of Prague’s Archbishop’s Seminary with the new video mapping Missing Interval.

One of the festival’s most anticipated moments will take place at the Old Town Hall, where Ukrainian artist Svitlana Reinish will present Living in Truth. The video mapping is inspired by the ideas and legacy of Václav Havel and explores themes of truth, freedom, justice, love and democracy.

Families can also enjoy a dedicated programme at Kampus Hybernská, including workshops combining light, animation and basic programming, as well as the interactive Sound Robot by Slovak artist Ján Šicko. Alongside the installations, the festival will offer Signal Forum, a conference focused on digital and creative culture, and a programme of official afterparties.

Of the 21 installations presented in 2026, 13 are freely accessible, while eight form part of the ticketed Signal INSIDE programme, which takes visitors into selected indoor venues across Prague. The festival installations are open from 7 pm to midnight each day.
