History grade
What drives Philomath’s History grade
On its age, its old homes and the National Register, Philomath is more historic than 50% of U.S. towns, #49 of 142 in Oregon. Its National Register listings hold the grade up; its age pulls it down.
B−
HistoryA character grade: shown, never part of Philomath’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 Philomath’s 5.3 sits near the middle of its state (56% of Oregon towns have fewer) while its 3 historic buildings outnumber those of 65% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from C+ to B. 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; Wikidata’s 1882 falls in the same era, so the grade doesn’t depend on which one is used.

What stands out about Philomath’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
Philomath was named after the Philomath College which was founded in 1867 by the United Brethren Church. The college opened its doors in October of that year, with enrollment the first day at about 100. The first teachers were Joseph Hannon, who acted as principal, and Elisha Woodward, teacher in the primary department. The name of the college and city was derived from two Greek words meaning "lover of learning". The city was incorporated on October 20, 1882. The college closed in 1929 due to a dramatic decline in enrollment.
