What drives Lyme’s History grade
On its age, its old homes and the National Register, Lyme is among the most historic 1% of U.S. towns. All 3 inputs put Lyme near the top nationally; its age ranks highest.
A+
HistoryA character grade: shown, never part of Lyme’s overall grade.
New Hampshire towns list more on the Register than most of the country (a typical New Hampshire town has 9.5 per 10,000 residents, the U.S. 2.4), so Lyme’s 608 sits above most of its state (97% of New Hampshire towns have fewer) while its 104 historic buildings outnumber those of 90% of U.S. towns.
NoteThe founding year comes from Wikidata alone; no second source gives 1761.
How sure. Graded on any two of the three inputs instead, the letter would still be A+. The pre-1940 share is a Census survey estimate (±6.7 points).
Founding year: Wikidata (other dates in Quick answers). Homes: Census ACS 2020–24. National Register: National Park Service, May 2026 list; each listing counted once (boundary changes and added documentation belong to their listing), and a historic district counts its contributing buildings.

What stands out about Lyme’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
This was once a home to Abenaki Indians, including a band of Sokokis near Post Pond at a place they called Ordanakis. Later, it would be among the many towns granted by colonial Governor Benning Wentworth along the Connecticut River in 1761. Many of the 63 grantees lived in Massachusetts and Connecticut, but virtually none of them ever settled in Lyme, and they instead sold or assigned their grants to others. However, those settlers who did arrive in 1764 were mostly from those states. The town encompasses land that, prior to the Lyme's founding, was called Tinkham town. In the late 1770s, Lyme petitioned (ultimately unsuccessfully) to join Vermont.
