GUIDED VISITS

Transformed in 1904 by architect Paul Hamesse, the former Cohn-Donnay Hotel forms a refined and eclectic Art Nouveau ensemble. The tour offers an in-depth reading of this exceptional building, from its 19th-century origins to the emergence of Art Nouveau in the early 20th century.

Advertising poster for the event ‘Les Visites Hallucinées’ by ‘Philippe Baudot & Suzanne Dietz’. The image shows a middle-aged man in a dark suit, holding a magnifying glass to his eye, in an ornate hotel interior. The title ‘Les Visites Hallucinées’ appears at the top in cream-coloured lettering. The authors’ names are at the bottom. An intricate Art Nouveau frame surrounds the scene

HALLUCINATORY VISITS

De Ultieme Hallucinatie is an Art Nouveau jewel whose walls conceal many mysteries. The Hallucinated Tours invite you to (re)discover this iconic place by following the playful investigation of a witty detective and his inseparable sidekick.
A unique opportunity to explore more than 180 years of history (and stories) within one of Brussels’ most extraordinary buildings. More than a visit, a quirky and surprising journey with Philippe Baudot and Suzanne Dietz.

The experience continues around a meal included in the package, extending the adventure in a convivial and gourmet spirit.

BANAD FESTIVAL

Every spring, Brussels opens the doors to some of its most beautiful buildings. The BANAD Festival invites visitors to explore Art Nouveau and Art Deco venues that are usually closed to the public. Over three weekends, the city reveals itself in a new light, through its interiors, staircases, stained-glass windows and salons. During the final weekend, on 28 and 29 March 2026, guided tours will be organised at De Ultieme Hallucinatie, and the brasserie will exceptionally open its doors on Sunday. As a festival partner, the venue will also welcome visitors on Saturday for a drink or a meal. Because at De Ultieme Hallucinatie, Art Nouveau is as much to be savoured as it is to be admired…
