History grade
What drives Horicon’s History grade
On its age, its old homes and the National Register, Horicon is more historic than 88% of U.S. towns, #46 of 362 in Wisconsin. All 3 inputs are above most U.S. towns; its share of homes from before 1940 ranks highest and its National Register listings lowest.
A
HistoryA character grade: shown, never part of Horicon’s overall grade.
Wisconsin towns list more on the Register than most of the country (a typical Wisconsin town has 3.0 per 10,000 residents, the U.S. 2.4), so Horicon’s 10.5 sits above most of its state (77% of Wisconsin towns have fewer) while its 4 historic buildings outnumber those of 68% of U.S. towns.
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 (±5.4 points). The founding year is the first post office, not a stated founding date.
Founding year: the first post office (other dates in Quick answers). Homes: Census ACS 2020–24. National Register: National Park Service, May 2026 list; each listing counted once (boundary changes and added documentation belong to their listing), and a historic district counts its contributing buildings.

the town was in 1846, located on Section 3. Rev. James W. Burton preached the first sermon in the township in 1846, and, in the following year, the German Lutherans built a house of worship on Section 35. There are now in the town eight churches. Much of the history of this town will be found in the history of the village of Horicon, and therefore we give a very brief notice of many things. The first mill was built by Larrabee & Co. in 1847, on Rock River, in the present village of Horicon. The town is traversed by two railroads — the Chicago, Milwaukee & St. Paul, and Fond du Lac, Amboy & Peoria, the history of which is given elsewhere.

The erection of a dam across Rock River, near the village of Horicon, was commenced in 1845 and completed in 1846-47. A saw-mill was built, in connection with the dam, in 1847, and a grist-mill in 1848-49. In June, 1852, owing to an unusual accumulation of water above, the dam "went out." The break was nearly one hundred feet in width, and the united efforts of the citizens were required to stay the rushing waters. For six weeks, the work of depositing stones and trees and earth in the break went on, and it was not until the energies of the current had been spent, that the gaping chasm could be completely bridged. In the mean time, the land owners on the east side of the lake got out an injunction against the proprietors
