What drives Windsor’s History grade
On its age, its old homes and the National Register, Windsor is more historic than 32% of U.S. towns, #70 of 159 in Colorado. Its National Register listings hold the grade up; its share of homes from before 1940 pulls it down.
C
HistoryA character grade: shown, never part of Windsor’s overall grade.
Few Colorado towns list much on the Register (a typical Colorado town has 1.1 per 10,000 residents, the U.S. 2.4), so Windsor’s 0.5 sits near the middle of its state (48% of Colorado towns have fewer) while its 2 listings outnumber those of 60% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from C− to C+. The pre-1940 share (±1.3 points) is firm at this size. Two sources give 1882.

In 1873, a settler named J.L. Hilton built a small house situated half-way between Greeley and Fort Collins. The "half-way" house, as it became known, directed travelers along a route, which was soon adopted by the Greeley, Salt Lake and Pacific railway. The railroad brought investors and farmers to Windsor in increasing numbers. Windsor's rich alluvial plains lent themselves to extensive wheat production and the establishment of one of the town's first commercial enterprises, a flour mill, which through a subsequent fire in 1899, was rebuilt and became the Windsor Milling and Elevator Company.
