The Musée d'Orsay in Paris will present "J'ai vu," a museum-wide intervention by the American artist Jenny Holzer, from 20 October 2026 to 21 February 2027. Rather than occupying a single gallery, the project spreads through the museum's spaces, unfolding as a site-wide encounter with her text-based practice. The timing is significant: 2026 marks the 40th anniversary of the Musée d'Orsay, which opened in 1986 inside the former Gare d'Orsay railway station. The anniversary provides the frame for one of the most ambitious contemporary-art interventions the museum has hosted, handing its Beaux-Arts halls and platforms over to a living artist's language-driven work. Holzer is best known for projects that place short, pointed texts in public and institutional space — LED signs, projections and installations that borrow the language of advertising and political speech and turn it back on the viewer. A museum-wide format allows that strategy to operate at architectural scale, meeting visitors in corridors, atria and galleries rather than only in a white cube. For the Orsay, whose identity rests on 19th-century art, the invitation to Holzer signals a willingness to let contemporary voices speak across its historic collection. Holzer's work has long been concerned with how language operates in spaces of authority. Her best-known projects — scrolling LED texts, stone benches carved with statements, large-scale light projections on buildings — take over the surfaces of public life and fill them with voices that are by turns political, intimate and unsettling. In the Orsay, those strategies meet a museum whose own architecture was itself repurposed from a railway station, another kind of public space turned to new use. The result is a genuine meeting of two centuries of French cultural history. The show joins a dense Paris autumn season that also includes centenary programs at the neighbouring Musée de l'Orangerie.
