3 places in town are on the National Register, among them the Conrad Weiser House, a National Historic Landmark, and two historic districts with 16 buildings between them. Below: 2 old photos and papers, maps from 1902 on, and the census since 1980.
More historic than 90% of U.S. towns, on its age, its old homes and the National Register.
On its age, its old homes and the National Register, Heidelberg Township is more historic than 90% of U.S. towns. All 2 inputs are above most U.S. towns; its National Register listings ranks highest and its share of homes from before 1940 lowest.
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 Heidelberg Township’s 101 sits above most of its state (89% of Pennsylvania towns have fewer) while its 18 historic buildings outnumber those of 79% of U.S. towns.

Each neighbor’s History grade, on the same three inputs.
Heidelberg Township is more historic than 90% of U.S. towns. The History grade combines the town’s founding era, the share of homes built before 1940 and its National Register listings. It’s a character grade, so it isn’t part of the overall grade. How it works.
Three places: the Conrad Weiser House (listed 1966), the Kissling Farm (1992) and the Stupp-Oxenrider Farm (1992).
21% of Heidelberg Township’s homes were built before 1940 (Census estimate, ±7.2 points), against a typical 18% for a Pennsylvania town; the median home was built in 1970.
