Sonnenberg Gardens

Sonnenberg Gardens, also known as Sonnenberg Gardens and Mansion State Historic Park, is a 52 acre state park located at 151 Charlotte Street, Canandaigua, New York, USA, at the north end of Canandaigua Lake, in the Finger Lakes region of Upstate New York. The house and gardens are open to the public every day, May through October. Much of the signature floral design and landscaping seen today at our nine formal gardens bears the imprint of philanthropist Mary Clark Thompson, who brought home ideas and art from her many trips to European and Asian locales. Following the 1899 death of her husband, Mrs. Thompson involved hundreds of workers between 1902 and 1919 in a re-design of the gardens. She was assisted primarily by Boston landscape architect Ernest Bowditch, and later, his assistant John Handrahan.
