HistoryA character grade: shown, never part of Eagan’s overall grade.
Minnesota towns list about as much on the Register as the country (a typical Minnesota town has 2.1 per 10,000 residents, the U.S. 2.4), so Eagan’s 1.3 sits near the middle of its state (52% of Minnesota towns have fewer) while its 9 historic buildings outnumber those of 75% of U.S. towns.
How sure. Graded on two of the three inputs, so a change in either one moves the letter more than it would with three. The pre-1940 share (±0.4 points) is firm at this size.

What stands out about Eagan’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
Eagan was named for Patrick Eagan, who was the first chairman of the town board of supervisors. He farmed a 220-acre (0.89 km2) parcel of land near the present-day town hall. Eagan (born 1811) and his wife Margaret Twohy (born 1816) emigrated from County Tipperary, Ireland to Troy, New York, where they married in 1843. They arrived in Mendota circa 1853–54, before settling in the Eagan area.
