I remember Bologna’s Piazza Maggiore from my university days, like a grand, disciplined, stone-framed stage where rituals of civic life unfold with medieval composure. But this December, that stage it has been disrupted in a way few could have anticipated: towering inflated “rock” forms, luminous, uncanny and unmistakably out of place, appeared across the piazza, immediately igniting both awe and critique. This is IWAGUMI – Dismisura, an immersive installation by Melbourne-based art and technology studio ENESS, installed from 21 to 26 December 2025, freely viewable by day and night in the very heart of Bologna.

At first sight, the work feels like a visual contradiction: nineteen monumental megaliths, rising up to 14 meters high, cast an illusion of granite yet are composed of inflatable textile skins, illuminated and animated after sunset.

Whether you see them as alien monoliths, futuristic flora, or a surreal geological intrusion, they radically reorganize the familiar spatial choreography of one of Italy’s most historic cities.

Iwagumi - Dismisura in Piazza Maggiore, Bologna

The title and conceptual underpinnings draw from iwagumi, a Japanese aesthetic principle originating in rock arrangements for Zen gardens and aquascaping — where stones are harmoniously composed to invite contemplation.

ENESS reinterprets this minimalist tradition at an amplified scale, coining the term dismisura to emphasize deliberate exaggeration: an aesthetic of oversize that insists on reexamining our sense of proportion, context and presence.

But this is more than a formal game. The installation stages an explicit contrast between organic reference and urban history: soft, air-filled masses facing down the stone façades of San Petronio, Palazzo d’Accursio and Palazzo Re Enzo. It’s an act of spatial friction, a poetic charge that unsettles and seduces.

Iwagumi – Dismisura is conceived not just as a sculptural spectacle but as a living, responsive environment. By day, the forms command presence through scale and surface texture; by night, they shift. The installation lights up automatically at sunset, filling the square with chromatic moods inspired by natural landscapes, from hues echoing the Dolomites to ambient sounds derived from birdsong, water and original compositions that react to the presence and movement of visitors.

This sensory dimension, the interplay of illumination, sound and human engagement, positions the work within a lineage of large-scale, experiential public art. In Bologna, this fluid choreography of light and tone feels like a seasonal spell, intended to activate the piazza during the winter solstice and holiday period.

To understand Iwagumi – Dismisura, it helps to look at ENESS as a practice. Founded in 1997 by artist Nimrod Weis, ENESS has carved a distinctive niche at the intersection of sculpture, textiles, design, software, music and storytelling. Their approach doesn’t treat art as static objecthood but as atmospheric architecture and participatory choreography.

One of the studio’s most celebrated projects is Iwagumi Air Scape, a larger-than-life inflatable rock garden that has appeared in public spaces like Prahran Square, Melbourne and Singapore. There, sixteen air-filled forms with granite-like photographic surfaces invited visitors to walk among cavernous passages, prompting moments of discovery, play and reflection. As daylight fades, the work shifts, evolving lighting and soundscapes heighten the enchantment while suggesting nature’s presence in the urban, an interplay between wilderness and civic frame.

Air Scape exemplifies ENESS’s skill in balancing monumentality with tactility, and technology with poetry. The structures are monumental in their visual imprint but ephemeral in material, giving form to tension between permanence and impermanence.

Public reaction in Bologna has been as layered as the installation itself. Social media quickly buzzed with images of the towering inflatables, some praising the work’s spectacular reinvention of space, others questioning its material and contextual fit within a medieval cityscape.

The temporality of Iwagumi – Dismisura is central to its impact. Installed only for a brief window, the work refuses to settle into visual routine. Instead, it demands presence, movement and re-evaluation of the piazza, not just as backdrop but as active collaborator in meaning-making.

Seen through this lens, ENESS’s installation does more than occupy a square. It provokes awareness: of scale, of surface, of history, and of how visual languages from disparate cultures, Japanese aesthetics, inflatable technology, urban dynamics, can converge to produce something that unsettles as much as inspires.

Whether loved or contested, this explosion of soft stone in stone reminds us that public art, at its most potent, doesn’t decorate. It disrupts, re-frames and forces us to look, again, and with new eyes.
