Iron Garden formed an artificial field of flowers in the Hoogkoor . It consisted of two rows of swinging sticks to which 2,400 bells were attached. Obá invited visitors to walk along the 10-metre Path and set the 'field' in motion by hand. The bells refer to liturgical bells, but also to the signalling function of church bells to announce approaching danger. This ambiguity was also found in the other works. Two paintings hung at the end between the pillars and depicted intimate, imaginative, and at the same time disturbing scenes.
