In October, Prague will once again become a stage for light art as the Signal Festival returns for its thirteenth edition. Under the title Signal INSIDE, it unveils extraordinary interiors across the city. From a Gothic monastery to a modern club, international artists transform historical architecture into immersive worlds of light and sound.
This year, the Signal Festival celebrates its thirteenth edition from 16 to 19 October and expands its programme beyond the well-known large-scale video mappings and installations in public spaces. For the first time, seven artistic works will be presented in architecturally unique interiors as part of the paid zone Signal INSIDE. Visitors can look forward to an intimate atmosphere – from the projection by American video art pioneer Bill Viola at the Convent of St Agnes, to Robert Seidel’s large-scale projection MLHA at the Clam-Gallas Palace, or the dance and light performance Lone Soul Disco by Viktor Konvalinka and Štěpán Benyovszký at the Tresor Club.
Architectural history meets digital art
Signal INSIDE grants access to locations in Prague that are usually closed to the public and offers interactive, immersive experiences in which the audience often becomes part of the artworks themselves. “Each location represents different architectural styles spanning the centuries – visiting Signal INSIDE is also a journey through architectural history, from the Gothic Convent of St Agnes dating back to the 13th century to the modern Tresor Club,” explains the festival’s programme manager and curator, Alžběta Krajčíková.
Five of the seven installations come from international artists. The video projection Tristan’s Ascension (The Sound of a Mountain Under a Waterfall) by Bill Viola at the National Gallery’s Convent of St Agnes invites visitors to pause for contemplation. Robert Seidel’s site-specific projection MLHA transforms the Baroque façade of Prague’s Clam-Gallas Palace. Projected across all four walls, it combines light, fog and sound to completely envelop the audience.
Interactive works such as Proudy by the Dutch artist Roelof Knol at Kampus Hybernská respond to visitors’ movements – an experience for families and anyone curious. Spanish artist Josep Poblet transforms the Functionalist chapel of the Archbishop’s Grammar School with his light installation Lux Domus. Finally, at the Tresor Club, visitors can experience the dance and light performance Lone Soul Disco by Štěpán Benyovszký and Viktor Konvalinka.
Signal INSIDE is part of both festival routes: most installations are located on the Central Route, with two on the Vinohrady Route. This allows the paid programme to be easily combined with the free-access installations. A day ticket currently costs 390 crowns, while a four-day ticket is 490 crowns and includes a smartphone audio guide. The VIP ticket, priced at 1,690 crowns, offers priority access, a Mercedes-Benz VIP shuttle and entry to the new year-round gallery Signal Space.
The Signal Festival takes place from 16 to 19 October. Most installations are free to access. The full programme, routes, tickets and further information can be found at www.signalfestival.com.
