Seven Sisters

 Atop the most southerly hill in a chain known as the Seven Sisters, William Hooker Gillette, noted actor, director, and playwright, built this one hundred and eighty-four acre estate, the Seventh Sister. The focal point of his effort was a twenty four room mansion reminiscent of a medieval castle.
 Purchased by the State of Connecticut in 1943 from the executors of Mr. Gillette's will, Gillette Castle and the adjoining property with its fine woodlands, trails, and vistas are now administered for the enjoyment of present and future generations.

  This apparently would have pleased Gillette, since his will gave specific directions to see that the Connecticut River property did not fall into the hands  "of some blithering saphead who has no conception of where he is or with what surrounded."
