Walled City was exhibited at the Katonah Museum of Art, Katonah NY as part of the exhibition “Conversations in Clay” from October 2008-January 2009 

Walled City, an elaborate urban environment of interlocking walls and towers of brick and terra cotta, portrays a bleak and unforgiving industrial apocalypse. The materiality of earthenware clay and its long association with human civilization are central to the humanity projected by Arnie Zimmerman’s scenes and seemingly meaningless toil. In Walled City his figures labor anonymously, cast into a nameless urban environment whose walls merge with those of the gallery.”         - excerpted from exhibition catalog essay by Ursula Ilse-Neuman and Janet Kardon
