SpY Built a 20-Meter Black Triangle in Madrid and Wired It to CCTV Cameras Pointed at the Square

PANOPTICON blocks the view across Plaza de Cibeles with an opaque monolith, then lets visitors peer back through viewing apertures fed by live surveillance footage of the very square the structure is standing in.

Most public art installations invite you to look at them. PANOPTICON, a new work by Spanish urban artist SpY installed in Madrid’s Plaza de Cibeles, does something closer to the opposite: it blocks your view of the square, then hands it back to you mediated through the very surveillance system it’s examining.

A 20-meter monolith that refuses to be seen through

The installation is a large, opaque equilateral black triangle measuring 20 meters on each side, positioned directly in front of the historic Palacio de Cibeles — a deliberate, abrupt contrast between the dark, monolithic geometry and the ornate 19th-century facade behind it. Where most large-scale public installations try to blend into or complement their surroundings, PANOPTICON’s entire effect depends on cutting the established sightlines across the civic square, replacing an open view with a hard, obstructing form.

Looking back through the surveillance it blocks

The piece’s actual mechanism sits in its concealed viewing apertures, integrated along the triangle’s perimeter. Each aperture holds a display monitor wired to CCTV cameras mounted at the apex of the structure, high above the square. Step up to an aperture and the monitor shows fragmented, live footage of the surrounding traffic, pedestrians, and architecture — shot from an elevated, overhead vantage no pedestrian actually has.

That’s a direct, physical staging of Jeremy Bentham’s panopticon — the architectural model built around the idea that the possibility of being watched, more than the fact of it, is what disciplines behavior in a surveilled space. By making a visitor’s own act of looking depend entirely on routed camera footage of the square they’re standing in, SpY collapses the distance between “being watched” and “doing the watching” into a single physical object, rather than illustrating the idea abstractly.

Why the timing lands

PANOPTICON arrives as digital tracking and camera-mediated public space have become background facts of city life rather than novelties, which is exactly the terrain the piece is working. SpY isn’t the first artist to tackle surveillance aesthetics, but routing a real, working CCTV feed through a structure visitors have to physically approach and look inside — rather than displaying a screen, a projection, or a photograph of surveillance — gives the critique a bodily, site-specific weight that a gallery piece on the same theme generally can’t match.
