What drives Chelsea’s History grade

On its age, its old homes and the National Register, Chelsea is more historic than 84% of U.S. towns, #110 of 701 in Michigan. Its National Register listings hold the grade up; its age pulls it down.

A−
HistoryA character grade: shown, never part of Chelsea’s overall grade.

Few Michigan towns list much on the Register (a typical Michigan town has 0.0 per 10,000 residents, the U.S. 2.4), so Chelsea’s 111 sits above most of its state (94% of Michigan towns have fewer) while its 60 historic buildings outnumber those of 86% 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 is a Census survey estimate (±9.1 points). The founding year is the first post office, not a stated founding date; Wikidata gives 2004.

The story

How Chelsea came to be

From Wikipedia’s history of Chelsea.

Read it all →

The area was first settled as early as 1820 within the Michigan Territory by settler Cyrus Beckwith. It would be organized as Sylvan Township in 1834. The Michigan Central Railroad constructed a line through the area in 1848, and a post office was first established on January 4, 1849. It was originally named Kendon. The name was changed to Chelsea on July 19, 1850 when the train station opened and community was formally platted. The name Chelsea came from Elisha Congdon, who suggested the name after his hometown of Chelsea, Massachusetts. Chelsea incorporated as a village in 1889. The Chelsea courthouse is housed in a 120-year-old bank building in downtown.

Chelsea was without a passenger depot until recently, and the villagers and their friends were much gratified when the new and elegant station was opened to the traveling public in December, 1880. The depot, though not so magnificent as that of Jackson, excels it in architectural beauty, and is therefore one of the prettiest railroad buildings in the State.

Pierceville, at the junction of the north, south and Territorial roads, just south of the present village of Chelsea, on James Congdon's land, was a business center in 1834 and thereafter until the depot was located at Davidson Station, when the place was absorbed bv the new village, and one after another the buildings were sold, moved away or torn down. When Pierceville was in its glory, a brother of John C. Winans, Stephen by name, had a store there.
