Constructed in 1855 to replace the original station, Gerrish Depot is the oldest surviving depot on the former Northern Railroad. First known as North Boscawen Depot, it was renamed in 1909 following a fatal train collision caused by confusion over similar station names, along with several other depots on the line. The name Gerrish was chosen in honor of a prominent farming family. The depot provided freight and passenger service for local farms and residents, the state nursery, the county nursing home, and the county jail until 1955.
