Guillaume Bijl (born 1946, in Antwerp), is a Belgian installation artist.
Bijl is a self-taught artist. He followed a theater course and was first working as stage builder and painter. From the second half of the 1970s he started to create spatial objects and was researching in finding alternatives for conceptual art. Bijl's first installation was a driving school, set in a gallery-space in Antwerp in 1979, accompanied by a manifesto calling for the abolition of art centres, and replacing them with 'socially useful institutions'. This installation was followed in the eighties by a billiards room, a casino, a laundromat, a centre for professional training, a psychiatric hospital, a fallout shelter, a show of fictitious American artists, a conference for a new political party and a rural Belgian model house. A more recent show was at the Berlin’s Center for Opinions in Music and Art. Bijl is also an artist at the Mulier Gallery, has displayed at the Witte de With Center for Contemporary Art and has been reviewed by the New York Times.
He divides his work into four categories: 'transformation installations', 'situation installations', 'compositions trouvées' and 'sorry's'.
Bijl created a display window for a wax-doll museum for Documenta IX in 1992.
