Katonah in Westchester County, New York — The American Northeast (Mid-Atlantic)
The North Lawn
John Jay Homestead
From the top of this hill, the highest point on the property, much of the original Jay estate could be seen. During the early 1900s, the jays built a grass tennis court here. The court was later used for croquet. Across the fields to the south of the main house on another promontory once stood the 1852 home of John Jays grandson, John Jay II.
In 1925, Eleanor Jay Iselin, the great-great-granddaughter of John Jay built a childrens playhouse for her son Arthur Iselin, Jr. Today, a reconstructed playhouse contains a small exhibit on the structures restoration.
There was no garden in the courtyard when the Jays and Iselins lived here. Today, the Hopp Ground Garden Club maintains a garden here for the benefit of those who are unable to enjoy the unpaved gardens located in other areas of the site. This garden includes plant materials from these other gardens.
Erected by Friends of the Jay Homestead. (Marker Number 10.)

[ detail from the marker ]
The views highlighted in red on this map, ca. 1855, includes the location of John Jay IIs house and formal garden prior to his inheriting the Homestead. You may look at the view from the hill or the front lawn.
Archeological excavation revealed that the base of the tennis court was constructed by placing layers of cinders and coal ash, item in plentiful supply as waste from the Homesteads heating system, over a layer of rock and sand.
