Signal Festival is Prague's annual festival of light and digital art established in 2013. After it grew into an important cultural event in national context, its organisers created a permanent venue for digital art called Signal Space gallery, which opened on 1 October 2025 as part of the festival's programme.

Signal Space is part of a former municipal market hall in central Prague, near the Můstek metro station. The cast-iron building, with an arched central nave and clerestory skylights, was adapted as a permanent venue for digital art installations. According to Fisheye Immersive, the main gallery comprises about 1,300 square metres of modular exhibition space. The venue includes a large-format 360-degree projection hall and several smaller rooms, and hosts a rotating showcase of Czech artists.

The gallery's opening exhibition, Echoes of Tomorrow presented works by digital and media artists focused on technology, perception and the future. Featured works included Everything by the Istanbul studio Nohlab, intangible #form by Shohei Fujimoto, Fighters by Quayola and Max Cooper, a generative environment by Markos Kay, and the interactive Body Sketches / Scale Studies by Zach Lieberman. The gallery reported more than 70,000 visitors by March 2026, and the exhibition was extended in response to public demand.

Signal Space is part of the Prague-based organisation Signal, which also runs Signal Festival and the production studio Signal Creative. It was founded by Czech entrepreneur Martin Pošta.
