The luxurious lifestyle enjoyed by two wealthy 18th-century Connecticut Valley families—until their fortunes collapsed—is displayed in the Phelps-Hatheway House and Garden. Merchant Shem Burbank built the house in 1761. As a Tory sympathizer, his business suffered during the American Revolution. In 1788 he sold the house to Oliver Phelps, who in 1794 flaunted the riches earned from land investments in western New York by adding a wing, an architectural masterpiece that still features original Paris-made wallpaper. Eight years later Phelps left Suffield, bankrupted by his failed land schemes. The house is furnished with outstanding 18th-century Connecticut furniture and landscaped with formal flower beds. The Hatheway family owned the house throughout the 1800s, accumulating an attic full of artifacts that document life during that century.

The house offers tours.

Staatsburgh is a New York State Historic Site located within the boundaries of Mills-Norrie State Park. It provides an example of the great estates built by America's financial and industrial leaders during the Gilded Age. A 25-room Greek Revival structure was built on the site in 1832 by Morgan Lewis and his wife, Gertrude Livingston, replacing an earlier house that had burned down. This second house was inherited by Ruth Livingston Mills, wife of noted financier and philanthropist Ogden Mills. In 1895, Mr. and Mrs. Mills commissioned the prestigious New York City architectural firm of McKim, Mead, and White to remodel and enlarge their Staatsburg home. After completion in 1896, the house was transformed into a Beaux-Arts mansion of 65 rooms and 14 bathrooms. Its exterior was embellished with balustrades, pilasters, floral swags, and a massive portico. The rooms were furnished with elaborately carved and gilded furniture; fine oriental rugs; silk fabrics; and a collection of art objects from Europe, ancient Greece, and the Far East.

The site offers tours and educational and recreational programs and events.

The Society is committed to the preservation and interpretation of Arrowhead, home of author Herman Melville, the first National Historic Landmark to be so designated in Berkshire County. The author's study, piazza, the original fireplace from his short story "I and My Chimney" and the restored barn in which Melville and Hawthorne spent hours discussing their writings are all open to the public. The Society has also restored the North Meadow preserving the view of Mount Greylock which was a major inspiration to Melville.

The Society owns two Ripon houses, including one with a barn. The older of the two is the Pedrick-Lawson House which was placed on the National Register of Historic Places because of its unusual grout-block construction. Built in the 1850s, it is partially restored as it might have looked during the Civil War era. The barn is used for storage and exhibits including farm tools and equipment. A Victorian garden with markers identifying its various plants and flowers has been developed on the property. The newer of the two houses, the Pickard House, was built during the 1870s and has been remodeled and furnished to resemble a modest middle-class home in the early part of the 20th century. It contains the Society's archives, library, meeting room, and museum for both permanent and temporary exhibits. The museum collection includes Victorian and early-20th-century furniture and furnishings, men's and women's clothing, quilts and coverlets, tools and equipment for various trades and occupations, dishes and glassware, and works of art by Ripon artists. Special collections of such items as local business and professional records and artifacts, wedding dresses, children's toys, games and dolls, and war memorabilia are featured in our permanent and changing exhibits.

The Society operates two house museums. The 1872 Lee House was home to Dr. Norman Lee, one of Junction City's first doctors. It was originally located in Lancaster and was moved to its present location in the late 1800s using logs and a team of horses; it now displays photos, furniture, tools, and clothing from Junction City's past. The 1871 Pitney House belonged to Mary Pitney (1891—1995), a school teacher, published poet, painter, world traveler, and humanitarian. Born and raised in this house, she lived the later years of her life here; today, it is being restored and features a room devoted to Danish historical artifacts from Junction City's first settlers, a cutaway of the home in the kitchen so visitors can see how buildings were constructed in that time period, and Mary's original furniture in the living room. Next door to the Pitney House is the first jail, built in 1873.

The houses offer exhibits, tours, and occasional recreational and educational events.

During the 1790s, James Vann became a Cherokee Indian leader and wealthy businessman. He established the largest and most prosperous plantation in the Cherokee Nation, covering 1,000 acres of what is now Murray County. In 1804 he completed construction of a 2-and-a-half-story brick home that was the most elegant in the Cherokee Nation. After Vann was murdered in 1809, his son Joseph inherited the mansion and plantation. Joseph was also a Cherokee leader and became even more wealthy than his father. In the 1830s almost the entire Cherokee Nation was forced west by state and federal troops on the infamous Trail of Tears. The Vann family lost their elegant home, rebuilding in the Cherokee Territory of Oklahoma. Today the Vann House survives as Georgia's best-preserved historic Cherokee Indian home. A guided tour allows visitors to see the house which features hand carvings, a "floating" staircase, a 12-foot mantle, and fine antiques.

The site offers tours, exhibits, a film, demonstrations, and recreational and educational events.
