This summer, for the first time since Duke closed it, the estate will be open to the public for limited tours.
The public will see the original 700-acre bull's eye of the property: the hay barn, the mansion, waterfalls, lakes, fountains, bridges, meadows and woodlands created by Olmstead's firm. The tours will run Wednesday through Sunday from June 4 to November 15. The display gardens, which reflect the cultures and climates of a dozen different regions around the world, are not open during the summer.
