Historic Resource Mapping

Chester County's character is largely defined by its historic resources and cultural heritage landscapes. In addition to hundreds of locally designated historic resources in our municipalities, Chester County ranks second in the state in the total number of individually-listed properties and districts listed in the National Register. Explore this map to find out more information about these National Register properties and districts.

Historic Resources Atlas Projects

In 2004, an update to the original Chester County Historic Sites Survey (1978-1982) using a Geographical Information System (GIS) was initiated. This initiative is a partnership between the Planning Commission, Chester County Historic Preservation Network, and the municipalities. This project provides the first digitization of existing Chester County historic resources data and verifies the original survey data. The Atlas identifies historic resources (buildings, structures, sites, and objects) that are 50 years and older as a starting point and follows National Register of Historic Places criteria as a guideline. It is being completed on a municipality-by-municipality basis with the primary assistance of municipal historical commission members and interested volunteers and, in some cases, supplemented and expanded upon with the assistance of a professional consultant using County Vision Partnership Program grant funding. As of January 2020, 40 municipalities have completed Atlases and several other municipalities have Atlases underway.
