Castles of the World — 9,040 castles, fortresses & palaces

A curated, hand-checked dataset of the world's 9,040 great castles, fortresses, palaces and ruins across 155 countries — every landmark verified to have exact coordinates, a real Wikimedia Commons photo and a Wikipedia article.

Fields: Wikidata QID, name, category (castle/fortress/palace/ruin), country, ISO 3166-1 code, WGS84 coordinates, founding year and century (with an approximation flag), English Wikipedia URL, Commons photo URL with its photographer credit and licence, Wikipedia sitelink count, trailing 60-day pageviews summed across language editions, a global fame rank (rank 1 = the Great Wall of China) and the landmark's page URL.

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.
