The 184.5–mile Chesapeake & Ohio Canal National Historical Park preserves the history of this canal, which shipped coal, lumber, grain, and other agricultural products along the Potomac River. The canal's story intertwines with those of western expansion, transportation, engineering, the Civil War, immigration, industry, and commerce. Rangers provide a mid–19th–century living history experience, and the park also offers an option of staying overnight in one of several historic lockhouses–each with interpretive media and furnishings which simulate the living conditions of the lock keeper's family during the 1830s, Civil War, the early 1900s, or the 1950s.

The park offers two replica canal boats, drawn by mule; docents in period dress; ranger–led hikes, walks, lift lock demonstrations, power point presentations, and mule programs; canal boat tours; Junior Ranger activities; and a period room overnight experience. The website offers lesson plans, photo galleries, and a coloring page.

The Thaddeus Kosciuszko National Memorial consists of the home of the Polish head engineer of the United States' Continental Army, Thaddeus Kosciuszko (1746-1817). The majority of the house is dedicated to exhibits concerning Kosciuzko's life and career. However, one room has been furnished in period style. Visitors to the home during Kosciuzko's life included Benjamin Rush, Thomas Jefferson, and Chief Little Turtle; and in his will, Kosciuszko asked that his property in the United States be sold to purchase the freedom and education of slaves.

The memorial offers an eight-minute introductory audio-visual program, exhibits, a period room traveling trunks, and Junior Ranger activities.

The Justin Smith Morrill Homestead preserves the Greek Revival cottage of John Smith Morrill (1810-1898). During his life, Morrill worked as a blacksmith, merchant's clerk, Representative, and U.S. Senator. Unable to finish school himself, Morrill became the chief sponsor of the 1862 Land Grant Act. The act provided for a college in each state which would teach skills not previously available in the higher education system—practical science, agriculture, and engineering. These colleges also offered more traditional studies. Morrill's hobbies included architecture and landscape design.

The homestead offers period rooms, tours, gardens, and access to Morrill's library. Please call ahead to verify admission hours. Appointments are required for library access. The website offers suggested reading and a video virtual garden tour.

The Schell Memorial Bridge is a 515--foot long steel cantilever truss bridge donated in 1902 to the town of Northfield by one of its leading citizens, Francis R. Schell. The bridge spans the Connecticut River, uniting the east and west sides of Northfield. Unfortunately, lack of maintenance and funds led to the closure of the bridge in 1985. Friends of the Schell Bridge is dedicated towards the reopening of this historic bridge, even if it could only be reopened in a limited capacity, such as limiting the bridge to foot traffic and emergency vehicles only.

The site provides information about the preservation effort and the history of the bridge. In addition, the site has an archives of all newsletter put out by the organization, links to news about the bridge, and links to help preservation advocates get involved.
