	tl;dr: Castlemap is a free interactive map plotting 3,693 curated castles, fortresses, and palaces across 131 countries, with Italy (288), France (276), and Germany (254) leading in count. The data is sourced entirely from open sources—Wikidata for coordinates, Wikimedia Commons for photos, and OpenFreeMap/Natural Earth for the basemap—and the full dataset is downloadable as GeoJSON or CSV under CC0. Landmarks are ranked by "fame" using Wikipedia language edition counts, with Versailles topping the list.
	HN Discussion: ↓Dataset is severely incomplete due to reliance on English Wikipedia rather than OSM or other sources ↑Cool concept and fun discoveries like snow castles and Madagascar palaces make the map enjoyable ↓UI/UX issues like low contrast colors and cropped images hurt the experience ↓Categorization is inconsistent and lacks clear definitions for castle types ~The site is obviously vibe-coded with AI, which shows in its quality
