A curated, hand-checked dataset of the world's 2,400 great castles, fortresses, palaces and ruins across 131 countries — every landmark verified to have exact coordinates, a real Wikimedia Commons photo and an English Wikipedia article. Fields: Wikidata QID, name, category (castle/fortress/palace/ruin), country, ISO 3166-1 code, WGS84 coordinates, founding year and century, English Wikipedia URL, Commons photo URL, Wikipedia sitelink count, annual pageviews and a global fame rank (rank 1 = Palace of Versailles). This is the exact dataset behind the free interactive map at thecastlemap.com. Documentation, downloads and a live MCP query endpoint: thecastlemap.com/data/. Curated from Wikidata (CC0); photos and Wikipedia texts referenced by URL remain under their own licenses.
