Shortly after purchasing Turtle Bay Gardens, a complex of brownstone townhouses in New York City, socialite Charlotte Bronson Hunnewell began building a unique country retreat for herself and her husband, Dr. Walton Martin, in Cornwall, Connecticut. Dubbed "The Castle" by locals, the 8,412 square foot mansion was completed in 1924 and was used as a summer retreat. Charlotte added a pottery to the estate in 1927, hiring Vincenzo Rondinone to be her resident artist. Rondinone's Narrow Valley Pottery, and the Castle itself, became integral parts of Cornwall's history. The book is an adaptation of a lecture given by Cornwall resident Jeffrey Jacobson for the Cornwall Historical Society. It includes biographies of Charlotte Bronson Hunnewell and Vincenzo Rondinone and is illustrated by 21 historic and contemporary images.
