During WWII, a 26-acre make-believe village was constructed on top of Boeing's Plant II in Seattle to provide a wartime cover for the facility. Cottages were made of painted canvas, trees were constructed of wire mesh and wood covered with chicken feathers, and the lawn was actually green burlap. Construction of the Wonderland facility atop Plant II required one million board feet of lumber and one and one half million square feet of chicken wire. There were 500,000 feet of support wires and 500 tons of steel structures to support higher elevations. The camouflage extended beyond Plant II to neighboring Boeing Field, albeit in a more sparsely decorated fashion. When the illusory scene was dismantled by Army engineers in 1946, it was necessary to remove 42,000 square yards of dummy streets, 10,000 square yards of concrete dummy houses and walks, 85,000 yards of camouflage texturing from runways, paint from four buildings and blackout paint from one hangar.
