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.
