The oldest part of the courthouse building is a brick and granite two story structure, completed in 1857 to serve as a town hall and court building. The city and county used the building for town offices and county courts until 1904, when the city sold its interest in the building to the county. Between 1905 and 1907 the building was extensively remodeled to plans by local architect George S. Forrest.<ref name=NRHP>{{cite web|url={{NRHP url|id=79000202}}|title=NRHP nomination for Merrimack County Courthouse|publisher=National Park Service|accessdate=2014-03-07}}</ref> The courthouse has been listed on the National Register of Historic Places since 1979.<ref name="nris"/> As of 2018, a new courthouse had been constructed to the rear of the building, and county offices were to be moved into the original building.<ref>{{Cite news| url=https://www.concordmonitor.com/Merrimack-County-Superior-Court-renovation-update-18609481| title=Downtown: Merrimack County Superior Court renovation nears completion| last1=Andrews| first1=Caitlin| date=July 8, 2018| access-date=March 7, 2019}}</ref>
==Building history== The site where the courthouse stands has been used for civic purposes since 1790, when Concord, then a town, built a townhouse on the site. That building was enlarged in 1823 when Merrimack County was created, with Concord as its shire town. That building served both town and county functions until 1855. The present building was built in response to the need for more space by both governments, and was completed in 1857 to a design by New Hampshire native Joshua L. Foster. That design had more Classical Revival features than the building has now, with a mainly granite exterior, a {{convert|33|ft|m|adj=on}} dome on top and an arcaded front porch across the facade.<ref name=NRHP/>
The building served both city and county in that form until 1904, when the city sold its interest in the building to the county, and built a new city hall. The county then decided to renovate rather than replace the building, work which was completed in 1907. Significant alterations included the removal of the dome and arcade, construction of the Renaissance entry pavilion, and refacing the exterior in brick.<ref name=NRHP/> A modern wing was added to the front (east side) of the building in the 20th century.<!-- This wing was demolished in 2018 with construction of the new courthouse. Needs a cite. -->
