The Society operates the John Brown House Museum and the Museum of Work and Culture. The John Brown House museum was one of America's grandest mansions when completed in 1788, for John Brown, a businessman, patriot, politician, China Trade pioneer, and slave trader who participated in the debates and practices that shaped the new nation and the world. Today this building serves as a place in which the public can learn about the men and women who lived here from the late 18th through early 20th centuries. The Museum of Work and Culture presents the story of immigrants who came to find a better life in the mill towns along the Blackstone River. The exhibits recreate immigrant life at home, at church, and at school, and present the unique Woonsocket labor story of the rise of the Independent Textile Union, which grew to dominate every aspect of city life.

The 1678 Joshua Hempsted House is one of New England's oldest and best documented dwellings. Joshua Hempsted lived here his whole life, filling many roles, including farmer, judge, gravestone carver, shipwright, and father of nine children left motherless by his wife's death in 1716. The Hempsted House survived the 1781 burning of New London by the British, commanded by traitor Benedict Arnold. Later, it may have been a safe house on the secret Underground Railroad which aided fugitive slaves seeking freedom. Adjacent to the Joshua Hempsted House is a rare stone dwelling built in 1759 by his grandson Nathaniel. Both houses' furnishings include original Hempsted family objects.

The houses offer exhibits and tours.

The Museum of African American History is dedicated to preserving, conserving, and accurately interpreting the contributions of African Americans in New England from the colonial period through the 19th century. The Museum maintains several individual historical sites, including the Boston African Meeting House, the Abiel Smith School, the Nantucket African Meeting House, and the Higginbotham House. The African Meeting House on Beacon Hill was built in 1806 in what once was the heart of Boston's 19th-century African-American community. It is today a showcase of black community organization in the formative years of the new republic. The 1834 Abiel Smith School is the first building in the nation built for the sole purpose of serving as a public school for black children. This historic site has been transformed into exhibit galleries. The African Meeting House on Nantucket is the island's most vivid reminder of a thriving 19th-century African-American community. Erected in the 1820s by the African Baptist Society (of which Captain Absalom Boston was a trustee), it is the only public building still in existence that was constructed and occupied by the island's African Americans during the 19th century.

The museum offers exhibits, tours, educational programs, lectures, and recreational and educational events; the Boston African Meeting House offers tours; the School offers exhibits; the Nantucket African Meeting House offers exhibits.

The merchant James Rundlet acquired his wealth in the textile trade. To proclaim his success, he built his 1807 mansion on a terraced rise above the street and filled it with the finest furnishings available. He imported his wallpapers from England and purchased his furniture from local cabinetmakers, whose work was noted for its fine craftsmanship and striking use of veneer. Rundlet also saw to it that his house was equipped with the latest technologies. The kitchen boasts both a Rumford roaster and a Rumford range, as well as a set kettle and an elaborate venting system that services a smoke room on the third floor. There is an early coal-fired central heating system and an indoor well.

In the 19th century, Americans wanted more land and settlement moved west. For countless Indians, the American thrust for land meant the end of their traditional way of life. The Shawnee Mission was one of many missions established as a manual training school attended by boys and girls from Shawnee, Delaware, and other Indian nations from 1839 to 1862. Visitor to this 12-acre National Historic Landmark can learn the stories of those who lived there.

The Museum displays exhibits tracing the history of the New England whaling industry. The Hadwen House is a Greek Revival mansion built in 1845 by whaling merchant and silver retailer William Hadwen. Also called the Jethro Coffin House, the Oldest House is the oldest residence on Nantucket. Built as a wedding gift in 1686 for Jethro Coffin and Mary Gardner, it is the sole surviving structure from the island's original 17th-century English settlement. The Old Mill, built in 1746 by Nathan Wilbur, a Nantucket sailor who had spent time in Holland, is the oldest functioning mill in the country. The Old Gaol was opened in 1806; the wooden structure represents colonial architecture with exceptional reinforcements. The Quaker (Friends) Meeting House was erected in 1838 and originally served as a Friends School for the Wilburite Sect.

Old Town San Diego State Historic Park presents the opportunity to experience the history of early San Diego by providing a connection to the past. Visitors can learn about life in the Mexican and early American periods of 1821 to 1872, as converging cultures transformed San Diego from a Mexican pueblo to an American settlement. The core of restored original historic buildings from the interpretive period are complemented by reconstructed sites, along with early 20th-century buildings designed in the same mode. The Historic Plaza remains a gathering place for community events and historic activity. Five original adobe buildings are part of the historic park, which includes museums, unique retail shops, and several restaurants. La Casa de Estudillo is a mansion built around a garden courtyard.
