New Jersey towns list more on the Register than most of the country (a typical New Jersey town has 3.7 per 10,000 residents, the U.S. 2.4), so Wenonah’s 4.4 sits near the middle of its state (54% of New Jersey 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). Two sources give 1871.

What stands out about Wenonah’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
Wenonah was founded in 1871 by Philadelphia businessmen as a country resort, drawn by its location along the Mantua Creek and on the West Jersey Railroad. Over the next 40 years, numerous dams were installed to create recreational lakes. From 1902 until the Great Depression, Wenonah Military Academy, a private military school, trained cadets there.
Throughout its history, Wenonah has been almost exclusively a residential area. Over 21% of the borough's land area is conservation land, which is protected by ordinance from development. There are more than 6 miles (9.7 km) of hiking trails are threaded around lakes and alongside waterways in these conserved areas.
