More historic than 24% of U.S. towns. What drives it
Its Register listing is the Saint John the Baptist Catholic Church. Most of Frenchtown was built recently: 1% of its homes predate 1940 and the median home dates from 1993. Below: maps from 1959 on and the census since 2000.
The Frenchtown post office opened in 1868, the earliest record of the town by name.
More historic than 24% of U.S. towns, on its age, its old homes and the National Register.
On its age, its old homes and the National Register, Frenchtown is more historic than 24% of U.S. towns. Its National Register listings hold the grade up; its share of homes from before 1940 pulls it down.
Montana towns list more on the Register than most of the country (a typical Montana town has 12.7 per 10,000 residents, the U.S. 2.4), so Frenchtown’s 5.2 sits near the middle of its state (43% of Montana towns have fewer) while its 1 listings outnumber those of 51% of U.S. towns.
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.
