What drives East Lyme’s History grade
On its age, its old homes and the National Register, East Lyme is more historic than 61% of U.S. towns, #136 of 155 in Connecticut. Its age holds the grade up; its National Register listings pull it down.
B
HistoryA character grade: shown, never part of East Lyme’s overall grade.
Connecticut towns list more on the Register than most of the country (a typical Connecticut town has 73.3 per 10,000 residents, the U.S. 2.4), so East Lyme’s 6.9 sits below most of its state (5% of Connecticut towns have fewer) while its 13 historic buildings outnumber those of 77% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from C+ to B+. The pre-1940 share (±2.6 points) is firm at this size. The founding year is the first post office, not a stated founding date; Wikidata’s 1839 falls in the same era, so the grade doesn’t depend on which one is used.
Founding year: the first post office (other dates in Quick answers). Homes: Census ACS 2020–24.

What stands out about East Lyme’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
The Thomas Lee House, built c. 1660, is the oldest house in Connecticut that is still in its primitive state. This building is located in the southwestern section of East Lyme, adjacent to Rocky Neck State Park, at the intersection of Route 156 and Giants Neck Road. Co-located on this site is the one-room Little Boston Schoolhouse, which was relocated to its current location from across Route 156. The town features six homes from 1699 or earlier, and the Old Stone Church Burial Ground from 1719 located off Society and Riverview roads.
