What drives Westport’s History grade
On its age, its old homes and the National Register, Westport is more historic than 29% of U.S. towns, #297 of 362 in Wisconsin. Its share of homes from before 1940 holds the grade up; its National Register listings pull it down.
C
HistoryA character grade: shown, never part of Westport’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 Westport’s 0.0 sits below most of its state (28% of Wisconsin towns have fewer) while its 0 listings outnumber those of 23% 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 is a Census survey estimate (±6.9 points). The founding year is the first post office, not a stated founding date.

What stands out about Westport’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
The town was named after Westport, County Mayo, in Ireland because many of the early settlers were from there. The village of Waunakee was carved out of the town in 1893, leaving the remainder of the town on both sides. Other portions have been annexed by the cities of Madison and Middleton. A portion of the former Town of Madison on the northern shore of Lake Mendota was transferred to Westport.
In September 2024, the town's board of supervisors voted to support a petition to incorporate as a village, and it filed a petition with Wisconsin's Incorporation Review Board in July 2025.

The town of Westport derives its name from Westport, Ireland, from which place many of its early settlers came. The town is watered by the Yahara River, which enters the northeast part of the town on Section 13, and flows southwesterly into Lake Mendota, and also by Six Mile Creek, which enters the town on the northwestern part, on Section 6, flows southeasterly and empties into the Catfish on Section 27. The northeastern part of Westport is prairie land, the central and southeasterly portions marsh, and the remaining parts oak openings and prairie. Lake Mendota covers a part of five sections on the southern part.
