HistoryA character grade: shown, never part of Casco’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 Casco’s 18.9 sits near the middle of its state (56% of Maine towns have fewer) while its 7 historic buildings outnumber those of 73% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from B− to A−. The pre-1940 share (±2.6 points) is firm at this size. Two sources give 1841.

What stands out about Casco’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
On January 30, 1767, Raymondtown Plantation was granted by the Massachusetts General Court to Capt. William Raymond of Beverly, Massachusetts, and his company of soldiers for their service with Sir William Phipps in the 1690 Battle of Quebec. It replaced a 1735 grant called Beverly-Canada (now Weare, New Hampshire) which was ruled invalid in 1741 because of a prior claim by the heirs of John Mason. In 1803, Raymondtown Plantation was incorporated as Raymond. The town of Naples was created with land taken in 1838, the same year the western half of Raymond petitioned the legislature to be set off as a township because of its geographical separation behind Rattlesnake Mountain. The petition failed, but three years later another was accepted. On March 18, 1841, Casco was incorporated as a town.

All of the shore line visible from the Island was included in the two ancient settlements of Casco and Westcustogo, which, upon incorporation, were named Falmouth and North Yarmouth respectively. The boundary line established between these two townships bears away from the Ottawa House piazza about east of north, past the end of Lower Clapboard Island, and remains to-day the dividing line between the present towns of Falmouth and Cumberland. The line between Falmouth and Deering, upon the shore, is the Presumpscot River, which debouches between Mackey's

The combined force of French and Indians came into Casco Bay from the Kennebeck by way of New Meadows River, meeting no opposition from the scattered settlements whence the inhabitants had retired to the protection of Fort Loyal. They made their rendezvous on some of the islands, and soon spied out the weakness of the garrison, ascertaining quite well the number of English left after the departure of Captain Willard.
