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 щоденники учасників, and follow our Mastodon or Bluesky account.
