Long considered a pioneer creator of ecological artworks for urban environments, Alan Sonfist has been mixing human history and the natural environment since the mid-1960s. Incorporating concepts of an area's natural and cultural histories, Sonfist has developed landscape sculptures in such diverse areas as Tuscany, Italy; Duisberg, Germany; Pori, Finland; and Tampa, Florida. His work has ranged from inventing an interior landscape about the history of a museum building in Washington, D.C., to a seven-mile-long nature and sculpture trail in Palm Springs, California. Sonfist creates many of his projects through Natural/Cultural Landscapes, a corporation he established in 1998 for the purpose of creating environmental landscapes throughout the world.
