Pixels meet Prague at Signal Space, the city’s first digital art gallery

Secreted away in the heart of tourist Prague, Signal Space, a new digital art gallery from the group behind the annual Signal Festival, transforms a historic market into a year-round destination for light, technology, and creativity.

After three years of searching, the collective found the Old Town Market Hall, completed in 1896, with high ceilings and open floors ideal for large-scale projections. The long unused space now offers visitors an immersive experience that elevates pixels and lasers to the status of fine art.

“We are still quite fixated on traditional visual arts in the Czech Republic. This is another type of experience,” Martin Pošta, founder and curator of Signal Space.

Digital art, which uses technology as both a medium and a tool, often incorporates interactivity, projections, VR/AR, and AI, turning viewers into participants rather than passive observers.

Cities leading the field include Tokyo (teamLab Borderless), Paris (Atelier des Lumières), and New York (Whitney Museum), all increasingly integrating digital works into contemporary programming. The medium is meant to make art more experimental, participatory, and accessible.

Covering over 2,500 m², Signal Space features eight rooms with permanent installations, the CzechBox curatorial platform highlighting contemporary Czech artists, and the Signal Playground, an interactive zone for children.

“We tried to take the best artists currently working in the digital media sphere, using different technologies and creative approaches, and place them here,” says Pošta.

At its heart is Immersive Space, the largest projection hall in the Czechia currently showing Everything by Istanbul-based studio Nohlab, a work that fuses scientific data, philosophy, and audiovisual art into a striking sensory experience.

Japanese artist Shohei Fujimoto presents Intangible Forms, a laser choreography that became the most visited historic installation at Prague’s Signal Festival. Visitors can also interact with American creative coder Zach Lieberman’s Body Sketches, which transform their own movements into digital drawings in real time.

Another standout is the Infinity Room, developed in collaboration with Preciosa Lighting, where mirrors and 180 crystal cubes create the illusion of an endless, glittering expanse.

The inaugural exhibition, Echoes of Tomorrow, will run for six months, connecting science, nature, AI, and light.

This year’s Signal Festival kicks off Oct. 16–19, and features 20 installations across two routes (the center and Vinohrady) with 13 outdoor works free to the public and seven ticketed indoor locations. Pošta admits that the festival, now in its thirteenth year and drawing hundreds of thousands of annual visitors, can overwhelm.

“From an audience perspective, it’s much easier. You can pace yourself, choose when you want to visit the gallery, and experience Signal 365 days a year. The Signal Festival is hugely popular, which is wonderful, but it also has drawbacks. Because it’s free and attracts so many people, navigating the crowds—especially with small children or a stroller—can be challenging.”

After this year’s festival—must-sees include a monumental work by the late American artist Bill Viola at the National Gallery’s St. Agnes Monastery and video mapping on Old Town Hall—Pošta hopes Signal Space will continue to fill a gap in the Czech art scene.

“Prague has been missing a permanent gallery of this kind,” says Pošta. “Signal Space allows visitors to experience digital art in a way that’s immersive, interactive, and entirely new for the city.”
