HistoryA character grade: shown, never part of Altamont’s overall grade.
Tennessee towns list more on the Register than most of the country (a typical Tennessee town has 6.1 per 10,000 residents, the U.S. 2.4), so Altamont’s 22.7 sits above most of its state (76% of Tennessee towns have fewer) while its 3 listings 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 A−. The pre-1940 share is a Census survey estimate (±3.1 points). The founding year is the first post office, not a stated founding date.

What stands out about Altamont’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
Altamont was established in 1848 as a county seat for Grundy County, which had been created in 1844. General Adrian Northcutt, a prominent local farmer and military officer, was the prime advocate for the site's selection. The town's name comes from combining alto (meaning "altitude") and mont (meaning "mountain"). Although the Civil War somewhat stunted the town's growth, by 1870 Altamont's population had grown to 217.

The Altamont post office opened in 1845, the earliest record of the town by name (U.S. post office records).
