The Musée de la Grande Ardenne is presenting an exceptional retrospective dedicated to the painter Willoos: ‘Willoos, Life in Colour’. Conceived as a major event for the summer of 2026, this exhibition brings together more than sixty years of creative work and offers a comprehensive overview of a rich and unique body of work, spanning from the Ardennes to California, via Peru. Visitors are invited on a journey into a world of line, form and, above all, colour.
The exhibition brings together a rare collection of works from private collections – pieces that are usually rarely, if ever, shown to the public – as well as from museums, galleries and public institutions. This is a unique opportunity to admire, in a single exhibition, exceptional pieces brought together for the first time and to rediscover the artist’s work from a fresh perspective.
A publication accompanies this retrospective. A collective work, it brings together texts, memories and reflections from various contributors on the artist and his work. This warm and colourful book reflects the artist’s spirit and invites us to continue our exploration beyond the exhibition galleries.
