Dominique Ghesquière (1953, Pensacola, United States)’s works are inspired by manufactured objects, construction materials and fragments of landscape. She reproduces them by hand, often using unexpected materials to disrupt the viewer’s expectations. In this way, her sculptures function like trompe-l'œil, quietly disorienting, and charged with subtle illusion. Installed in space, they create a shift, inviting the viewer to question the nature of what they saw. Mur de sable (2008) is a sculpture that activates the space differently each time it’s shown. The installation protocol is flexible: the work may stand as a low barrier that alters how visitors walk around it, or it can duplicate the existing architecture. Never taller than knee height, it does not obstruct vision, allowing the eye to pass freely over and beyond it. From a distance, it resembles a traditional wall, with an orderly pattern of stacked bricks. Yet its colour is unusual, and up close, the illusion unravels. The apparent solidity of the brick is contradicted by its actual material – sand – rendering the structure fragile, uneven and unstable. This tension between visual certainty and material vulnerability generates a quiet ambiguity, unsettling the boundary between reality and representation.
