No architect has influenced Oregon so broadly as John Yeon. A planner, conservationist, historic preservationist, art collector, and urban activist, as well as one of the state's most gifted architectural designers, Yeon was one of the progenitors of the Northwest Regional Style of architecture and stands among the region's most influential conservationists.The John Yeon Center is devoted to preserving Yeon's legacy by inspiring future acts of visionary architecture, urbanism, and conservation. A program of the School of Architecture and Allied Arts at the University of Oregon, the Center hosts events at two properties designed by Yeon: the 1937 Watzek House, Portland's only National Historic Landmark residence; and The Shire, a unique, 75-acre work of landscape design in the Columbia River Gorge.
