What drives Brownsville’s History grade
On its age, its old homes and the National Register, Brownsville is more historic than 77% of U.S. towns. Its National Register listings hold the grade up; its age pulls it down.
A−
HistoryA character grade: shown, never part of Brownsville’s overall grade.
Oregon towns list more on the Register than most of the country (a typical Oregon town has 2.9 per 10,000 residents, the U.S. 2.4), so Brownsville’s 94.1 sits above most of its state (94% of Oregon towns have fewer) while its 18 historic buildings outnumber those of 79% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from B− to A. The pre-1940 share is a Census survey estimate (±7.2 points). The founding year is the first post office, not a stated founding date; Wikidata’s 1876 falls in the same era, so the grade doesn’t depend on which one is used.

What stands out about Brownsville’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
Brownsville was originally known as "Calapooya" after the area's original inhabitants, the Kalapuya Native People, or "Kirk's Ferry", after the ferry operated across the Calapooia River by early settlers Alexander and Sarah Kirk. When Linn County was created from the southern portion of Champoeg County on December 28, 1847, the Provisional Legislature named Calapooia as the county seat. The Spaulding School in Brownsville served as the original county courthouse. Brownsville was named in honor of Hugh L. Brown, who settled there in 1846 and opened the first store.
In 1851, the Territorial Legislature passed an act establishing Albany as the county seat. A special election in 1856 reaffirmed Albany as the county seat.
Brownsville’s post office has been open since 1859. Another post office, Calapooya, opened and closed inside today’s town.
