Blithewold Manor and is located in Bristol, Rhode Island about an hours south of Boston on the Narragansett Bay. The first house was destroyed by fire and the second was built in 1906 in this English Country Manor style with Arts and Crafts style gardens. The photographs were sent to me by Nancy Feeman, who has written on gardens in England for this blog. Here is the website.
The house is in 33 acres of land which sits on the coast and so has spectacular views over the water. As well as the beautiful gardens there is a well developed arboretum. Thank you for sending these photos Nancy, I can't wait to go down and have look myself.
