Greenwich Historical Society was founded in 1931 to collect and chronicle this vibrant history and has actively pursued its mission since purchasing Bush-Holley House in 1957. It is a member of the Historic Artists Homes and Studios, one of 21 museums on the Connecticut Art Trail and accredited by the American Association of Museums.
Greenwich Historical Society boasts an extensive new research library and archives that contains more than 40,000 items; it is home to the Vanderbilt Education Center, which accommodates lectures, family programs and meetings, and may be rented for private events; and it includes the 1805 Storehouse Gallery, a former warehouse, store and post office that is now the location of administrative offices. The landscape and gardens are restored to circa 1900, the era when the Holley Boarding House, along with Cos Cob Village and harbor became one of the first American Impressionist art colonies.
The Historical Society is noted for award-winning school, after-school and summer camp programs; themed, docent-led tours of Bush-Holley House; lectures; rotating museum exhibitions; live storytelling programs; and Antiquarius, a suite of events that includes the Winter Antiques Show, Holiday Boutique and Holiday House Tour.
