What drives Pen Argyl’s History grade
On its age, its old homes and the National Register, Pen Argyl is more historic than 74% of U.S. towns, #421 of 1,035 in Pennsylvania. Its share of homes from before 1940 holds the grade up; its age pulls it down.

HistoryA character grade: shown, never part of Pen Argyl’s overall grade.
Pennsylvania towns list about as much on the Register as the country (a typical Pennsylvania town has 2.1 per 10,000 residents, the U.S. 2.4), so Pen Argyl’s 2.9 sits near the middle of its state (61% of Pennsylvania towns have fewer) while its 1 listings outnumber those of 51% 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 (±10.4 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 Pen Argyl’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
In 1853, Joseph Kellow discovered slate in the surrounding area, coining what is now known as the Slate Belt community. The name Pen Argyl originated from the Cornish name meaning "head" and the Anglo-Saxon name of Slate Rock, meaning "argylite". With the surge of quarrymen from Cornwall and England, the town expanded. Today, there is still one slate quarry in operation. Pen Argyl was once home to Lehigh and New England Railroad’s main freight yard and maintenance complex. The railroad’s roundhouse and shop building still stand just west of town along Pennsylvania Ave.
