The work was planted by Marinus Boezem (b. 1934) on April 16, 1987, in Southern Flevoland. The land art project was installed on polder land; 178 trees were planted on a knoll, a half-metre above the surrounding area. Over the following years, some trees were replaced due to deer damage, and stone was laid in the floor to echo the cross ribs and support beams of the cathedral.
