The platform's most atmospheric map: 29,160 castles across 116 countries, 98.6 percent carrying coordinates, so medieval Europe's defensive landscape ships as a scatter plot where the famous densities are visible from orbit: Germany holds 8,144, the United Kingdom 3,628, Italy 3,298, France 3,284, Spain 2,773, and Japan's 1,307 ride alongside as a parallel castle tradition. The roster is the full Wikidata castle class tree, chateaux, water castles, hill castles and tower houses included, with a Type column saying which and a purity guard that dropped 484 rows whose types showed no fortification signal at all (the class tree will happily offer a spa hotel that once had a tower). Dates honor the graph's honest unevenness: Built_Year appears only where construction is dated to a year or better (2,892 rows, Neuschwanstein's 1869 among them), Built_Century wherever any precision exists (4,807 rows; a castle built in the 1200s is century-true and year-NA, never a fabricated January 1st), and the century histogram peaks exactly where history says it should, 1,095 castles begun in the 13th century with the 12th and 14th flanking it. Condition is recorded on 3,107 rows in a conservator's vocabulary (1,506 demolished or destroyed, 835 ruinous, 599 preserved), heritage designation on 19,649, architectural style on 2,149, and 6,570 rows link their English Wikipedia article. Windsor Castle anchors the 11th century by test, year and century agree on every dated row by arithmetic, and coordinates all land on the globe. Built with an 11-test acceptance suite.
29,160 rows in one CSV file, with 13 columns in total: Castle, Castle_ID, Type, Country, Region, Built_Year, Built_Century, Condition, Style, Heritage_Status, Latitude, Longitude, Castle_URL.
