Empires rise and fall. Glaciers disappear. Languages and religions spread from one region to another. Simple dirt paths become busy highways and railways. Modest buildings give way to soaring skyscrapers. And you remember what your neighborhood used to look like. All of it belongs on OpenHistoricalMap.

Our growing community of volunteer contributors includes amateur and professional historians, OpenStreetMap and Wikipedia contributors, GIS specialists, and ordinary people knowledgeable about their surroundings. We are passionate about documenting the world and helping real-world communities tell their stories. To learn more about the community, consult our extensive wiki documentation, visit our discussion forum, read the brukardagbøker, and follow our Mastodon or Bluesky account.

You can start contributing to the map today by creating a free account. We also accept charitable donations through OpenStreetMap U.S., a 501(c)(3) nonprofit organization with tax-exempt status. Your generous donation will go directly toward keeping OpenHistoricalMap running smoothly for everyone.

The map on our homepage is just one of many ways to experience the historical information we’ve collected. The underlying data is available for reuse as a download or through various free APIs compatible with open source software.
