The Grantham Historical Society was established as a nonprofit organization to collect and preserve Grantham’s history and to generate interest in the town.

The archives, located at 34 Dunbar Hill Road, are currently closed due to coronavirus, but we’d love to hear from you. Please snail mail us at P.O. Box 540 Grantham, NH 03753; or send us an email at granthamhistory @

DRIVING DIRECTIONS: Grantham is located off Exit 13 of I-89. At the end of the exit ramps, turn left (coming from the south) or right (coming from the north) onto NH Route 10 South. Follow Route 10 through the village, and past the post office on the right. Turn right on Dunbar Hill Road, which is right after the green plank house. We are the second building on the right. No sign is visible as you approach, but you will see a parking lot in front of the building. Click here for a map: GHS map
