Casco was founded in 1990 in Utrecht, the Netherlands, as a platform for experimental art. Since 1996 Casco has developed a critical program that explores art in the public realm, questioning the relation between art and its physical, social and political environment. In 2005 Casco took the new title of ‘Office for Art, Design and Theory’. This title set an agenda more clearly focused on an interdisciplinary practice that addresses each of these areas independently, but also explores cross-fertilization, shared concepts, critical discourses, and connections to other fields. The relationship between theory and practice is central to Casco’s investigation within these fields.
