What drives Newcastle’s History grade
On its age, its old homes and the National Register, Newcastle is more historic than 92% of U.S. towns. All 3 inputs are above most U.S. towns; its age ranks highest and its National Register listings lowest.
A
HistoryA character grade: shown, never part of Newcastle’s overall grade.
Maine towns list more on the Register than most of the country (a typical Maine town has 15.9 per 10,000 residents, the U.S. 2.4), so Newcastle’s 31.4 sits above most of its state (67% of Maine towns have fewer) while its 6 listings outnumber those of 72% of U.S. towns.
NoteThe founding year comes from Wikidata alone; no second source gives 1753.
How sure. Graded on any two of the three inputs instead, the letter would range from A− to A. The pre-1940 share is a Census survey estimate (±5.2 points).
Founding year: Wikidata (other dates in Quick answers). Homes: Census ACS 2020–24.

What stands out about Newcastle’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
Originally known as Sheepscot Plantation, Newcastle was among the earliest European settlements in Maine, first established in the 1630s by fishermen and approximately 50 families. Settled in the early 1630s, Newcastle was the first town to be incorporated within the colonial territory of Sagadahoc. The settlement was part of the broader English colonization efforts along the Maine coast during the early 17th century, following the failed Popham Colony of 1607-1608.
