In Central and southern Europe, post-World War II landscape planners devised imaginative solutions in or near urban centers. One of the most ambitious examples is the 1972 Olympic site, 1.5 miles from center of Munich. The center of the project, a one-time airstrip, exhibition ground, and dump site for subway excavations, roughly 1 square mile in area, metamorphosed into a dynamic combination of landscape and architecture under the guidance of Gunter Behnisch, who envisioned an ‘’Olympic in Green’’ where buildings, landform, and flora fuse to produce an environment which would inspire a festival attitude. Behnisch's concept was to use landscape as the prime spatial element. He achieved this objective by interweaving all architectural elements with the landscape, and by avoiding spatial disconnection : the stadium appears to emanate from landform; the natatorium glistens in natural light; water, hills, and paths allow visitors to see and feel naturalistic forms and materials. Tension structures, inspired by Ewald Bubner, carry the lines of the landforms into the architectural elements, further enhancing spatial unity.
