It had been raining for days. The kind of slow, persistent rain that stretches a journey longer than it is. By the time I arrived in Wuppertal, everything still felt slightly muted, held back. Then the road began to climb. A taxi ride up the hill, leaving the city behind in small increments. Streets turning into curves, curves dissolving into green. And suddenly, the perspective shifts. The Skulpturenpark Waldfrieden sits above the city like a threshold, almost detached from it. Wuppertal spreads out below, while up here, the air feels clearer, quieter. You arrive and it feels elevated. Not just physically. Almost like stepping into a different register. The rain has stopped by then. Light breaks through in a restrained way, catching on the trees, on the paths still damp from the weather. You walk for a few minutes through the park, gravel under your feet, before the exhibition begins to reveal itself.

Three glass pavilions, placed within the landscape. Transparent, open, never fully closed off. Between them, sculptures extend into the park. Further up, the Villa Waldfrieden holds smaller, quieter works. Nothing is isolated. Everything exists in relation to its surroundings. The tour is led by Tony Cragg, who founded the park and still shapes its rhythm. His presence feels less like a guide and more like part of the structure itself, moving through the spaces, allowing the works to unfold without forcing them into explanation. Inside the first pavilion, Rebecca Horn’s works begin to move. Not dramatically. Not all at once. But steadily.

A tower of ladders rises into the space, unstable, interlocked, leaning into itself. Turm der Namenlosen (1994). At first, it appears as a construction, almost architectural. Then the movement begins to register. Motorized violins are embedded within the structure. They activate, producing fragments of sound that never fully gather into a composition. The work was first realized in Vienna in response to the Yugoslav wars, referencing displaced musicians playing in staircases and underground passages. That context remains present, but not as a narrative. It lingers as an atmosphere. The ladders suggest ascent, but they do not offer direction. They hold each other in place. A structure built out of imbalance, out of dependence. It feels fragile. And at the same time, fixed.

In the central pavilion, the tension sharpens. A grand piano hangs upside down from the ceiling. Concert for Anarchy (2006). At intervals, it opens violently. The keyboard is pushed outward by pneumatic force, exposed for a brief moment before being pulled back inside. The instrument closes again, only to repeat the gesture. The cycle is relentless. Sound is implied, but never allowed to unfold. The piano behaves like a body caught in repetition, unable to stabilize its own expression. Each opening feels like an attempt. Each closing is a withdrawal. The work doesn’t escalate. It insists.

Nearby, the pace shifts. A low, horizontal structure stretches across the floor. Hauchkörper (2017) Thin brass rods extend upward, slowly changing direction. The movement is so minimal it almost disappears. You don’t see it immediately. You notice it over time. It feels like breath. Not metaphorically, but physically. A quiet expansion and contraction, occupying space without demanding attention. The work resists spectacle entirely. It asks for duration.

In the lower pavilion, movement becomes accumulation. A mechanical device sprays black ink onto the wall in a steady rhythm. Malmaschine (1999). What emerges is a gestural image, something that reads as expressive, almost painterly. But the process is entirely automated. There is no hand. Only repetition. Layer after layer builds up, the surface becoming denser, heavier. The marks feel immediate, yet they are produced through a system that continues regardless of presence. It draws. Without stopping.

Close by, a different kind of encounter unfolds. Two mechanical arms move toward each other, each ending in a metallic rhinoceros horn. Kuss des Rhinozeros (1989). When they meet, a spark appears. Brief, precise, almost intimate. Then they separate. And begin again. The gesture repeats, holding a strange tension between aggression and closeness. The title suggests a kiss, but the contact carries force. Something collides before it connects.

Across the three pavilions, these works begin to form a field. Not through similarity, but through a shared condition. Movement is constant, but never neutral. It carries weight. Memory. Pressure. Rebecca Horn’s early work began with the body, with extensions, with devices that altered its reach, its limits. Those Körperextensionen emerged out of a period of isolation, after a severe poisoning during her studies left her hospitalized for an extended time. The experience shaped a practice that would continue to revolve around fragility, constraint, and the desire to exceed them. In these later works, the body is no longer visible. But it remains present. Displaced into mechanisms. Into gestures that repeat, hesitate, and interrupt themselves. The machines do not replace the body. They continue it in another form.

Sometimes delicate. Sometimes violent. Often both at once. The architecture of the Skulpturenpark intensifies this. The glass pavilions never fully separate inside from outside. Light shifts constantly. Trees move in the background. Weather becomes part of the experience. The works absorb these changes. They don’t stand apart from the landscape. They exist within it. Between the pavilions, sculptures extend into the park. The movement continues, more dispersed now, less contained. And in the Villa Waldfrieden, the scale contracts. Smaller works, quieter gestures. Feathers move slowly in Parrot Wings Blue (1993), mimicking the soft rhythm of flight. A stone opens and closes in Magic Rock (2005), revealing a crystal hidden inside. The same logic persists. Something concealed. Something revealed. But never fully. By the time you step back outside, the light has shifted again. The city is still there, below, but it feels distant now. The park holds its own rhythm, its own time. And the works remain in motion, even when you’re no longer watching them.  A sense of movement that doesn’t resolve. A tension that continues quietly, without insisting on being understood. Rebecca Horn’s works don’t ask to be read. They ask to be stayed with.
