GWINN, ONE OF THE BEST-PRESERVED ESTATES of the Country Place Era, was originally the home of Cleveland industrialist William Mather. It has survived as an important American work of art that today tells a story about early twentieth-century landscape style, economics, and social history.

Three innovative landscape architects collaborated on the project for more than two decades: Charles A. Platt, the architect who adapted the Italian villa to an American setting; Warren H. Manning, the well-known landscape architect, planner, and designer of parks in several states; and Ellen Biddle Shipman, who brought a new American sensibility to the art of garden design.
