Gregory Castiglia French, b. 1979
Industrial metal turned into skin, light and movement.
Gregory Castiglia assembles thousands of stainless steel nuts into bodies.
From a distance, a silhouette, a dancer, a bust. Up close, the material reveals itself: industrial steel, bolted piece by piece, letting the daylight through. That is the paradox of his work, and his signature: sensuality achieved with the most unforgiving of materials.
Born in 1979 and based in Ventabren, near Aix-en-Provence, he has devoted himself entirely to sculpture since 2021.
His sculptures, from table size to life size, are stable over time and immune to corrosion: they belong equally in a contemporary interior, a garden or an architectural project.
Gregory Castiglia grew up near Paris, between an entrepreneur father and a painter mother: two legacies he never separated. Self-taught, he left Paris in 2013 for Provence, the Mediterranean region that suits him. In 2021, after twenty-two years in the events industry, he turned his workshop into a laboratory and devoted himself fully to creating.
His gesture is simple to describe and long to carry out: welding, one by one, thousands of stainless steel nuts until a figure takes shape, then varnishing the whole. Fire is part of the process, as it is in bronze casting. Yet what emerges is anything but industrial: fluid bodies, taut curves, faces that light passes through.
Light is his real material. The gaps between the nuts let the eye through, reflections shift with the hour and the season, and the sculpture is never quite the same twice. That is what makes it sit so well against contemporary architecture, glass and the pale stone of the South. Some pieces can also be customised: they can be powder-coated in a wide range of metallic shades, close to automotive paints, to match a particular setting. The "Masque" is also available with a gold or silver leaf finish. And for seafront projects, the artist uses marine-grade stainless steel, even more resistant to salt spray. Allow one to two months for a bespoke piece.
His practice extends to design furniture as well.
Since 2023, his sculptures have been shown in Marseille, Saint-Tropez, Monaco, Athens, Miami and Atlanta. In the summer of 2024, an exhibition was devoted to him at the Renaissance Aix-en-Provence, part of the Marriott group.
Art Thema represents Gregory Castiglia, opening its catalogue to a contemporary material that naturally extends the standards it applies to bronze: stainless steel. His works are especially suited to architecture, hospitality and high-end interior projects, indoors as well as outdoors.
