An official Path Through History Site! Sonnenberg Gardens & Mansion State Historic Park is one of the longest surviving estates from the Victorian Era in the US. The elegant 40-room Queen Anne-style mansion was built in 1887 by NYC financier Frederick Ferris Thompson and his wife, Mary Clark Thompson, as a summer home. Between 1901 and 1920, the widowed Mrs. Thompson and her staff created the nine formal gardens seen today. The grounds are open to the public from May 1 - October 31 each year. The Finger Lakes Wine Center at Sonnenberg, housed in the historic Bay House near the conservatory, features some of the best wines from more than 40 partner wineries. For a nominal fee, visitors can taste selections from wines from the rotating-inventory tasting bar in the Wine Center. Some of Sonnenberg's special events include the Father's Day Car Show (June), Moonlight Stroll Music Series (July & August), and Arts at the Gardens Fine Art & Fine Craft Show & Sale (August) featuring 100 top quality artists from across the country. Educational gardening and horticulture classes are available.
