History grade
What drives Oswego’s History grade
On its age, its old homes and the National Register, Oswego is more historic than 77% of U.S. towns. Its National Register listings hold the grade up; its age pulls it down.
A−
HistoryA character grade: shown, never part of Oswego’s overall grade.
Kansas towns list more on the Register than most of the country (a typical Kansas town has 5.1 per 10,000 residents, the U.S. 2.4), so Oswego’s 36.1 sits above most of its state (88% of Kansas towns have fewer) while its 7 historic buildings outnumber those of 73% of U.S. towns.

Jesuit Missionaries from Osage Mission (now St. Paul, Kansas) who worked among the Osages called the village "Little Town," probably because the band of Osages who lived in the village were of the "Little Osage" division of the Osage People. More specifically, the Osage Village of Little Town was described as "Little Town Above" by the Jesuits, to distinguish it from another village, which was sometimes located just to the east of Little Town, called "Little Town Below." While Osage villages were moved quite often (according to weather, hunting conditions, and sanitary conditions) Little Town Above was generally located on the bluff overlooking the Neosho River, where Oswego sits today. Little Town Below often sat near Horseshoe Lake, in the Neo…
