Located on the historic Cos Cob Harbor, home of Connecticut's first art colony, the Society's facilities include the National Historic Landmark Bush-Holley House (c. 1730); the Visitor Center, housed in a former village post office (c. 1805); the Hugh and Claire Vanderbilt Education Center, set in a mid-19th century barn and artists' studio; and the William E. Finch, Jr. Archives.

Bush-Holley House is the centerpiece of Bush-Holley Historic Site on Cos Cob Harbor. A unique dual interpretation provides visitors with two distinct museum experiences that portray the history of the house: the era of the Bushes, a colonial family who lived and farmed on the site from 1790 to 1825, and the Cos Cob art colony period from 1890 to 1920. Eight rooms tell a story of change over time, beginning with the turn of the 20th century and moving backward in time to the Federal era. On the outside the historic buildings, landscape and gardens are restored to c. 1900.

The society offers exhibits, educational programs, research library access, and recreational and educational events; the Bush-Holley Historic Site offers tours and occasional recreational and educational events.

Winterthur, an American country estate, is the former home of Henry Francis du Pont (1880–1969), an avid antiques collector and horticulturist. In the early 20th century, H. F. du Pont and his father, Henry Algernon du Pont, designed Winterthur in the spirit of 18th- and 19th-century European country houses. Visitors to Winterthur will rediscover America's heritage through its collections of antiques and Americana and venture out over the fields and farmland to learn about the workings of a great American country estate. They can also wander through the 60-acre naturalistic Winterthur Garden, while children will wonder at the Winterthur's famous fairy-tale children's garden, Enchanted Woods, and enjoy hands-on learning in the Touch-It Room.

Mission Mill Museum interprets the history of the Thomas Kay Woolen Mill which produced wool products from 1889 to 1962 and represents one of Oregon's earliest and strongest industries.

The missionaries brought formal education, industry, and large scale agriculture and advocated for U.S. government in the Oregon country. The Museum preserves Mission houses; an Oregon Trail settler's house; a historic church; and the structures, equipment, and original water-powered turbine of the Thomas Kay Woolen Mill with related artifacts. The museum's two histories are shared with visitors through individual and group tours, interpretation, speakers, living history, children's programs, hands-on activities, and special events.

Confederate Memorial Park is the site of Alabama's only Old Soldiers Home for Confederate Veterans. In operation from 1902 to 1939, the home cared for elderly veterans, and wives and widows of veterans. The site included 22 buildings consisting of cottages; a hospital; dairy barn; mess hall; an elaborate water and sewage system; and Memorial Hall, an administration building which held offices, a library, and a large auditorium. The home served between 650 and 800 residents. The majority of veterans served in Alabama outfits, but many were from other Confederate states and moved to Alabama after the war. The last veteran died at the home in 1934. The facility closed in 1939 when the five remaining widows were moved to Montgomery for better care.

The site offers exhibits, tours, educational programs, and occasional recreational and educational events.

Idaho Territory was less than 10 years old when the territorial prison was built east of Boise in 1870. The penitentiary grew from a single cellhouse into a complex of several distinctive buildings surrounded by a high sandstone wall. Convicts quarried the stone from the nearby ridges and completed all the later construction. Over its century of operation, the penitentiary received more than 13,000 convicts, of whom 215 were women. Spurred in part by conditions that sparked a general riot in 1971 and an even more severe riot in 1973, the inmate population was moved to a modern penitentiary south of Boise and the Old Idaho Penitentiary was closed on December 3, 1973. Visitors begin with a video presentation recalling prison history, notorious inmates, and daily prison life. Once inside the Yard, they can imagine life in the foreboding sandstone cellhouses, see the contrasting beauty of the historic rose gardens, and view the effects of the 1973 riot. They may also visit Solitary Confinement, known as "Siberia," as well as Death Row and the Gallows.

The site offers a short film, exhibits, and educational programs.

The Sam Azeez Museum of Woodbine Heritage was created to remember and record Woodbine's past while also actively collecting the materials to preserve its continuing heritage. It is a destination for visitors and a local resource for the entire Woodbine community so that they may continue to use the Woodbine Brotherhood Synagogue building as a place to come together. Built by the early Woodbine colonists, the synagogue is listed on the National Register of Historic Places. The sanctuary has been restored and is available for special worship services. The lower level, Brotherhood Hall, houses the museum's permanent and temporary exhibitions. Also included is a community sculpture, the Collective Memory Wall, where the Woodbine community has contributed personal memories of Woodbine.

The museum offers exhibits and occasional recreational and educational events.
