The Historic County Borders Project

The Historic County Borders Project digitised the borders of the historic counties of the UK and has made them freely available for public and commercial use. The data can be downloaded below.

The project's aims and methodology are described in detail in the Project Description.

The project is closely based on the Historic Counties Standard, which provides a comprehensive definition of the names, areas and borders of the historic counties of the UK. Users of the data from the Project are advised to become familiar with the Standard. The Historic Counties Standard contains two definitions in relation to the treatment of detached parts. The data for both definitions (A and B) are provided.

The data are available in 6 formats:

The full (1:5,000) resolution versions are suitable for detailed large-scale mapping. The simplified versions are more likely to be suitable for use with small-scale mapping.
