The World's 2,400 Castles

6 hours ago

Castlemap is a free interactive map of 2,435 castles, fortresses, and palaces across 129 countries.
The map is built entirely from open data: Wikidata, Wikimedia Commons, Wikipedia, OpenFreeMap, and Natural Earth.
It curates only verified landmarks with real photos, English Wikipedia articles, and exact coordinates, balancing countries for explorability.
Users can add missing castles by improving their Wikidata entries (coordinates, photo, English article) for the next refresh.
The full dataset is free to download as GeoJSON or CSV under CC0.
France has the most castles (183), followed by Italy, Germany, England, and Japan.
Each castle has a 'fame score' based on Wikipedia language editions; Versailles ranks #1.
The atlas is curated, not exhaustive, focusing on significance over quantity.
