NHDHR, explains the program thusly:
New Hampshire’s historical highway markers illustrate the depth and complexity of our history and the people who made it, from the last Revolutionary War soldier to contemporary sports figures to poets and painters who used New Hampshire for inspiration; from 18th-century meeting houses to stone arch bridges to long-lost villages; from factories and cemeteries to sites where international history was made.There is a map on the site, which also provides photos and GPS coordinates of each marker.
Say, you're heading up to the Lakes Region for some foliage. You can look at the list of markers arranged by town for Ossipee, or Tamworth, or whatever town you're headed to. Before you go, or after you return, check out our New Hampshire history section in 974.2 for more history than can be placed on a roadside marker! In our reference section we have many town histories, so if you're interested in Ossipee, you can find Ossipee, New Hampshire, 1785-1985: A History [R 974.2 OSS].
Enjoy a little NH beauty, learn a little history, and have a great roadtrip!
