Built in 1889 in the Stick–Eastlake Style, but one that is also heavily influenced by the Greek Revival, it is listed on the National Register of Historic Places for its importance as a community/social center for the town.

Citizens' Hall was constructed by the Town of Lyndeborough between September 1888 and January 1889 to house the Lafayette Artillery Company's armory and its annual February 22 Levee and Ball.

Over the course of the next several months, construction of what would become Citizens' Hall was delayed as a group of townspeople petitioned the Hillsborough County Superior Court to overturn the town's March vote.

During the summer prior to construction, the Citizens' Hall building committee—composed of Civil War veterans and local politicians Jason Holt, B.G.

Herrick, and Fred Richardson, as well as Lafayette Artillery members Andy Holt and Charles Henry Holt—designed a simple structure resembling the nearby Baptist Church.

The facade includes a cross-gabled hip roof, and the front porch a decorative truss and diagonal support braces typical of this style.

The pine trim was painted an off-white color, in contrast to the medium-grey plaster walls, and the wainscotting and plank floor were stained brown.

Ten days later, former Artillery captain Joel Tarbell and his wife, Esther, held the first public event in the hall's history: their golden wedding anniversary.

In the late nineteenth and early twentieth centuries, the Artillery shared Citizens' Hall with the Grand Army of the Republic's Harvey Holt Post.

The GAR was responsible for introducing Memorial Day celebrations into Lyndeborough, and Citizens' Hall played an important role in the annual occasion.

By the 1950s, as interest in the Lafayette Artillery Company ebbed and the Washington's Birthday celebration ceased as an annual event, the condition of Citizens' Hall declined.

Occasionally the town would spend money to repair the structure, as in the 1950s when the Board of Selectmen voted to purchase new windows, replace sills, and add a second-floor fire-escape door to the building.

A $20,000 renovation—utilizing volunteer labor—resulted in the construction of bathrooms, the introduction of a heating unit, and moderately better insulation for the building, but much of Citizens' Hall's charm was covered or painted over.

Rust spots became noticeable on the ceiling, the floor became worn under the desks and chairs of department personnel, and artifacts were screwed, taped, or otherwise affixed to the plaster walls and wood wainscoting.

The first floor looked even worse, as the Board of Selectmen made a decision to forego basic maintenance in an effort to persuade the town to vote on the building's future.

Initially, the Selectmen and the town supported a renovation project that included digging out the basement of the building for use as storage space and, perhaps, a police department.

A third plan, offered by budget committee members Wayne Fullerton and Burton Reynolds, involved the allocation of $186,600 to renovate the first floor of Citizens’ Hall and address the building's major structural problems.

To oversee the renovation, the Board of Selectmen appointed a building committee consisting of builder Phil Brooks, former selectman Bill Stephenson, and three other local residents.

Brooks, who contributed tremendous amounts of time and materials to the project, coordinated volunteer efforts with Worcester, while Holland and Holt initiated the demolition and construction stages of the renovation.
