[3] New Boston is home to the annual Hillsborough County Agricultural Fair and the Molly Stark Cannon.

The 1743 cannon, which appears on the town seal, was given by General John Stark to the New Boston Artillery Company after the Battle of Bennington.

At the time, lands to the west of the Merrimack River, disputed between the two provinces, were treated by Belcher as part of Massachusetts, and he granted the town to several Boston families.

When the town was incorporated in 1763, Governor Benning Wentworth formally recognized the long-used name of "New Boston".

The town is home to the 2,800-acre (1,100 ha) New Boston Space Force Station, which started as an Army Air Corps bombing range in 1942.

In July 2021, the facility was given its current name and began operating as part of the United States Space Force.

Joe English Hill, elevation 1,285 feet (392 m) above sea level and the highest point in the town, is in the south.

New Boston is part of New Hampshire's 2nd congressional district,[10] represented by Democrat Ann McLane Kuster.

New Boston's fairgrounds are host to several events each year, including the Hillsborough County Fair, which usually takes place in September.

The fair helps to preserve the agricultural roots of the area, and families can enjoy rides, exhibits, and the famous tractor pull.

[11] The Fourth of July celebration is one of the larger productions in the area, starting with a parade featuring an assortment of floats created by locals, marching bands, and emergency vehicles, winding through the center of town and ending at the fairgrounds.
