MADmusée, Art museum in Avroy district, Liège, Belgium.

The Trinkhall Museum occupies a 1960s pavilion in Parc d'Avroy, wrapped since 2020 in a translucent shell of polycarbonate panels on a 21-metre steel lattice. A mushroom-shaped concrete column supports a round exhibition room; the old brick walls remain visible inside. The collection holds about 3,500 works, shown on 400 m² plus 200 m² of temporary space.

The Créahm association, founded in Liège in 1979 by Luc Boulangé, opened workshops for artists with mental disabilities; from these grew the Centre d'Art Différencié, which became the MADmusée in 1998. In 2020 the museum reopened as the Trinkhall Museum after a renovation by the Beguin-Massart firm that doubled its floor area to 1,800 m². The building stands on the site of the 1880 Café Trinkhall, a Moorish-style pavilion with two copper domes that was demolished in 1961.

The museum's name recalls the Café Trinkhall, a Moorish-style drinking hall with two copper domes that stood here from 1880 to 1961; "Trink" comes from the German word for drinking. Its programme is built on the notion of "arts situés", which treats each work as tied to the workshop where it was made rather than to a medical or occupational setting.

The museum stands in Parc d'Avroy, its entrance set back beneath the oval volume on a tapering concrete column. The ground floor holds the bookshop, library, café and temporary gallery around the old pavilion; the former roof terrace, now enclosed, serves as exhibition space. Large windows look onto the park and into the 1960s brick pavilion.

The 2020 renovation by the Beguin-Massart office wrapped the 1960s pavilion in a translucent shell of multilayer polycarbonate panels, carried by a 21-metre steel lattice on columns; the building glows at night. A new mushroom-shaped concrete column holds a round exhibition room, and the old brick walls of the pavilion remain visible inside.
