Castles API
Castles around the world as an API — 17,000+ castles from Wikidata with their country, geographic coordinates and the year they were built. Search and filter castles by name, country and build-year range, or find every castle near any coordinate by great-circle distance (perfect for "castles near me" features). Spanning Germany, Italy, France, Spain, the UK and 100+ countries, it is ideal for travel, tourism, maps, history, education and trivia apps. Open data from Wikidata.
