History & Founding

Located in the southwestern corner of New Hampshire, this county holds a significant place in the state’s history and boasts a diverse landscape and thriving communities. Established in 1769, it was originally known as Hillsborough Precinct, carved out of the larger Province of New Hampshire. The name honors John Wentworth, 2nd Baron of the Manor of the Isle of Wight, who was appointed as Hillsborough's proprietor. Interestingly, Wentworth initially attempted to establish a proprietary colony separate from New Hampshire, but this effort ultimately failed, and the region was reintegrated. The county played a crucial role in New Hampshire’s early development, serving as a gateway for westward expansion and settlement. A fascinating anecdote from its early days recounts the story of a runaway slave, Samuel Slater, who fled England and found refuge in Hillsborough County, eventually revolutionizing the American textile industry with his innovations.

Geography & Landscape

The county’s geography is remarkably varied. Situated in the Merrimack River Valley, it encompasses rolling hills, fertile farmland, and sections of the scenic Monadnock Region. The Merrimack River and its tributaries provide vital water resources and contribute to the area’s agricultural potential. While no major mountain peaks reside entirely within the county's borders, the presence of Mount Monadnock, a prominent peak visible from many locations, defines the southwestern skyline. The climate is characterized by four distinct seasons, with warm, humid summers and cold, snowy winters. Average annual rainfall is ample, supporting robust plant life and contributing to the region’s natural beauty. The land area spans approximately 877 square miles, a mix of developed areas and preserved natural spaces.

Economy & Communities

The county’s economy is a dynamic blend of urban, suburban, and rural influences. Nashua, the county seat, is a major commercial and industrial hub, while Manchester, just outside the county’s borders, exerts a significant economic pull. Major towns within the county include Merrimack, Amherst, and Bedford. Historically, agriculture played a vital role, and while it remains important, the economy is now dominated by manufacturing, technology, healthcare, and finance. Notable employers include BAE Systems, Saint-Gobain, and Dartmouth-Hitchcock Medical Center. The area is characterized by a mix of established industries and emerging tech companies, contributing to a generally prosperous environment. While some areas retain a rural charm, much of the county has experienced significant suburban growth in recent decades.

Points of Interest

Points of interest abound throughout the county. The Hillsborough Historical Society Museum offers insights into the region’s rich past. Numerous parks and conservation areas provide opportunities for outdoor recreation, including hiking, biking, and fishing. The annual Nashua Arts Festival draws large crowds, showcasing local talent. The county has also produced several notable residents, including former New Hampshire Governor John H. Sununu. A unique fact is that Hillsborough County consistently ranks among the fastest-growing counties in New Hampshire, reflecting its desirability as a place to live and work. The county’s strategic location, combined with its quality of life, continues to attract new residents and businesses, solidifying its position as a vital component of New Hampshire’s landscape and economy.
