The Rokeby Museum embarked earlier this year on a project, curated by Ric Kasini Kadour, to utilize the historic buildings and grounds as a platform for contemporary art. “Structures” is the second of two such exhibitions this year. Building-related artworks by Meg Walker, Axel Stohlberg, Denis Versweyveld, Judith Rey, Rob Hitzig, Steve Hadeka, Yoko Ono and the late Beverly Buchanan reflect on, respond to or contrast with 11 existing locations while giving them new purpose.
