Why it matters
Castlemap maps 2,400 curated castles, fortresses, palaces, and ruins worldwide, giving each landmark an exact location, image, founding information, and links to related Wikidata and Wikipedia records.
Its downloadable CC0 GeoJSON and CSV data make it useful for spatial history, teaching, and exploratory research on fortifications and palaces. Researchers can reuse the location and chronology data directly or connect its Wikidata identifiers to other datasets.
