World Historical Gazetteer

linking knowledge about the past via place

The World Historical Gazetteer is a platform for linking historical place records and making spatial connections across time and language.

  • Index of place records with coordinates, historical metadata, linked toponyms, and ecological classifications
  • Geocoding services

You can explore World Historical Gazetteer without a User Account! But do please sign up to stay up to date with WHG news and announcements. You will be required to sign up only if you want to download or create datasets or collections.

Existing users: Please log in to access your datasets, collections, and personalised features.

The WHG Index can be queried in two distinct ways:

  • Web Site: An interactive web platform for searching by name or location, viewing metadata on a map, and exploring datasets using visualisation tools.
  • API (Application Programming Interface): If you are a developer, you can use a programmatic interface for querying WHG data, performing spatial queries, and accessing geocoding services from external applications. See Swagger Documentation.

WHG offers three pathways for using its tools and services to augment and publish historical place data.

Explore tools and example lesson plans for incorporating historical geography into your teaching. WHG supports place-based learning across humanities disciplines.

The World Historical Gazetteer documentation offers detailed guidance for contributors and developers: how to submit datasets, understand the WHG data model, use the API, and run the platform locally.

Whether you're exploring as a researcher or building on WHG as a developer, the documentation provides the technical and procedural support you need.
