West Virginia towns list more on the Register than most of the country (a typical West Virginia town has 29.6 per 10,000 residents, the U.S. 2.4), so Nitro’s 1.5 sits near the middle of its state (37% of West Virginia towns have fewer) while its 1 listings outnumber those of 51% of U.S. towns.

What stands out about Nitro’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
Nitro was incorporated in 1932 by Circuit Court. Its name was selected by the United States government because of the establishment there, during World War I, of a large federal plant for the manufacture of explosives. The name Nitro derives from nitrocellulose, the main ingredient in smokeless gunpowder. Daniel C. Jackling "supervised the construction and operation" of the plant, which by the time of the armistice "was producing one hundred thousand pounds of high explosives per day." The city is known as "a Living Memorial to World War I."
