The Society is housed in the Jonathan Bourne Historical Center, built in 1897 by Emily Howland Bourne as a town library and as a memorial to her father, Jonathan Bourne, for whom the town was named. The Society also manages the Aptucxet Trading Post and the Briggs-McDermott House. The Trading Post recreates the first trade house built in 1627, by Plymouth Colony, located on the south bank of the Manomet (Monument) River, which is now part of the Cape Cod Canal. The Pilgrims traded with the Indians and the Dutch from New Amsterdam (New York City), thus having a source of income by which their debt to the London backers of their expedition to the New World could be repaid. The Trading Post site also houses Gray Gables Railroad Station, built for the personal use of President Grover Cleveland during the years of his presidency (1893–1896). The Greek Revival-style Briggs-McDermott House has been restored and furnished to reflect the period from 1840 to 1910, an important time for the Briggs family and Bourne.

The society offers lectures and occasional recreational and educational events; the center offers tours, exhibits, and research library access; the Trading Post offers tours; the Briggs-McDermott House offers exhibits and tours.

Mount Vernon was the beloved home of George and Martha Washington from the time of their marriage in 1759 until General Washington's death in 1799.

Visitors are invited to tour the Mansion house and more than a dozen outbuildings including the slave quarters, kitchen, stables, and greenhouse. They can stroll four different gardens, hike the Forest Trail, and explore the "George Washington: Pioneer Farmer" site, a four-acre working farm that includes a recreation of Washington's 16-sided treading barn.

This building was the capitol for only four days in 1855, but many believe that the actions of the legislature that met here led directly to the Civil War. Governor Andrew Reeder picked this location, away from the proslavery influence of Missouri, where the legislature would choose a permanent seat of government, create a constitution, and decide if Kansas would be a free or slave state. Instead the legislature kicked out the antislavery members and passed a bill to move the government to Shawnee Mission near the Missouri border. Inside this native stone building visitors will learn the stories of the antislavery and proslavery people of territorial Kansas, set alongside the beauty of the Kaw River Nature Trail.

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

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. La Casa de Machado y Stewart is full of artifacts that reflect ordinary life of the period. Some of the other historic buildings include the Mason Street School (California's first public schoolhouse), La Casa de Machado y Silvas, the San Diego Union Printing Office (site of the city's oldest surviving newspaper office), and the first brick courthouse. The Seeley Stables Museum, with newly rehabilitated exhibits on overland transportation, houses one of the finest wagon and carriage collections.
