There is the still-standing home of a man who signed the Declaration of Independence. Relics of old businesses and architecture abound. And there are an awful lot of covered bridges.
The register of historic places, run by the National Park Service, was started in 1966 to identify and protect historic resources, and now includes more than 90,000 properties such as buildings, sites and districts. Nominations are reviewed, and photos and associated documents are posted on a searchable database online.
About this list
This list of Lehigh and Northampton counties’ historic sites was compiled based on the historic register’s database. They are listed here in alphabetical order, and by last name in the case of some of the historic homes.
Pennsylvania’s records are not all digitized in one place, however. Notes and photos from the register and other sources , including the lehighvalleylive.com archives, are included where available.
Some entries appeared multiple times, like different sections of the Lehigh Canal, but were compressed for this list. Boundaries for historic districts are listed as they appear on the register, and some of these sites may also be known by different names.
