Historic Environment Record

The HER is managed and organised on a computer database, which is combined with Geographical Information System (GIS) mapping technology. The computer database is supplemented with various types of information, such as plans, photographs, reports, books, maps, etc, which can be in hard copy or digital formats.

Councils, developers, consultants, academic researchers and members of the public all use the HER.

Currently, Durham's HER has approximately 25,000 records (August 2023). There records are constantly being edited and updated as new research or finds are continually added.

Any research requiring up-to-date results should be made by consulting our Archaeology Section directly. This is essential if your enquiry concerns any planning matters.

Some information from the HER is available to the public through the Keys to the Past website. This website contains an edited version of both Durham and Northumberland County Council HER's. It is a useful tool for local researcher but should not be used to inform planning application supporting documents as it does not have all the data available.

Please note that archaeological contractors / heritage professionals must not use "Keys to the Past" as a primary source for planning reports. The National Planning Policy Framework (NPPF) clearly states in Section 12 paragraph 128, that the primary source to be consulted for heritage issues is the county/local HER.

Historic landscape Characterisation information is also available to view at Historic landscape characterisation or to download at Archaeology Data Service: County Durham and Darlington Historic Landscape Characterisation (HLC).

The information on the HER is copyright to Durham County Council.
