The Merrimack County Bank Building
Walking along North Main Street in Concord, this stately brick building immediately caught my attention. Its elegant Federal architecture, tall windows, and classical entrance suggest that it has witnessed much of the city’s history. As I discovered, it certainly has.

Completed in 1826, the building was constructed as the home of the Merrimack County Bank, one of New Hampshire’s earliest financial institutions. At a time when Concord was emerging as the state’s political and commercial center, the bank played an important role in supporting local businesses, merchants, and the region’s growing economy. Nearly two centuries later, the building remains one of the finest surviving examples of early nineteenth-century commercial architecture in the city.
What makes this building especially interesting is that it became much more than a bank. The upper floors housed the offices of lawyers, physicians, and other professionals, including Franklin Pierce, who practiced law here before becoming the fourteenth President of the United States. Concord historian Reverend Nathaniel Bouton also maintained an office in the building, devoting much of his life to documenting the history of the city and the state.
Beginning in 1840, another distinguished tenant arrived when the New Hampshire Historical Society established its headquarters on the third floor. As its collections continued to grow, the Society eventually purchased the entire building in 1869. For more than seventy years, priceless manuscripts, artifacts, portraits, and documents preserving New Hampshire’s history were housed within these walls. Even after the Society moved to its purpose-built headquarters on Park Street in 1911, this building continued to serve as a museum until 1952.
Like many historic buildings, its purpose evolved with the needs of the community. During the twentieth century it became home to an insurance company before beginning another chapter as the offices of Gallagher, Callahan & Gartrell, one of New Hampshire’s oldest law firms. While its occupants have changed, the building has remained an important part of Concord’s civic and professional life.
One of the greatest surprises in exploring history has been discovering how much I never knew about my own hometown. I had walked past this building countless times without realizing it had once housed a bank, the law office of a future president, the New Hampshire Historical Society, and a museum preserving the state’s history. It reminds me that we often travel great distances searching for remarkable stories, only to discover that some of the most fascinating chapters of history have been quietly waiting for us just around the corner.
