Castles tools (7)

write = sends, deletes, buys or posts
  • castles_nearFree

    List landmarks within a radius of a WGS84 coordinate, nearest first, each with distance_km. Radius defaults to 100 km (max 2,000). For "castles near <place>", geocode the place yourself, then call this with its latitude/longitude.

  • get_castleFree

    Fetch one landmark’s full record by slug (preferred, e.g. "palace-of-versailles") or exact name: coordinates, founding year and century, worldwide fame rank, photo URL with photographer credit and licence, Wikipedia link and its readership signals (Wikidata sitelinks, Wikipedia pageviews over the last 60 days summed across its largest language editions). Unsure of the slug? Call search_castles first.

  • get_statisticsFree

    Headline statistics computed live from the atlas: totals by type, top countries, busiest founding century, oldest landmarks, geographic extremes and the most famous entry. The source for claims like "which country has the most castles" or "when were castles built"; the full write-up lives at thecastlemap.com/statistics/.

  • list_countriesFree

    Every country in the atlas with its landmark count, most first — answers "which country has the most castles" (France leads). Returns country name and ISO code per row; country pages are browsable from the countries_index URL.

  • random_castleFree

    One random landmark with its full record, optionally limited to a country — for discovery, quizzes and "castle of the day" features.

  • search_castlesFree

    Search the atlas’s 9,040 castles, fortresses, palaces and ruins by name (accent- and case-insensitive substring match). Optionally filter by country (name or ISO code) and category. Results come best-match-first, then by fame; each has coordinates, founding century, fame rank and links to its atlas page and Wikipedia. If nothing matches, retry with a shorter fragment of the name.

  • top_castlesFree

    The most famous landmarks worldwide or in one country, ordered by Castlemap fame rank — a blend of Wikipedia coverage and readership; rank 1 is the most famous (Great Wall of China). The direct answer to "most famous castles in <country>"; filter by country and/or category.

Castlemap MCP server

A Model Context Protocol server for the Castlemap atlas: 7,786 castles, fortresses, palaces and ruins across 141 countries, with coordinates, founding dates, categories, fame ranking and Wikipedia summaries.

It is already running. Point a client at the hosted endpoint — there is no install, no signup and no API key:

https://thecastlemap.com/mcp

Streamable HTTP, stateless, POST-only (a GET returning 405 is correct). Protocol revisions 2025-06-18 and 2025-03-26 are accepted.

    "castles": {

Tools

Data

Derived from Wikidata, with summaries from Wikipedia and images from Wikimedia Commons. The atlas is curated rather than exhaustive: it covers castles with a documented history, a real photo and exact coordinates, not every earthwork and ruin.

The factual records are released as CC0 and downloadable as GeoJSON and CSV from thecastlemap.com/data — also mirrored on GitHub, Hugging Face, Kaggle and Zenodo (concept DOI 10.5281/zenodo.21322359, which always resolves to the newest version).

Running it yourself

server.mjs has zero dependencies — no SDK, no node_modules. It needs Node 18+ and a castles.geojson to read (download one from /data):

CASTLES_GEOJSON=/path/to/castles.geojson PORT=8891 node server.mjs

It binds 127.0.0.1:8891 by default; HOST, PORT and CASTLES_GEOJSON override that. The file is re-read when its mtime changes (throttled to 60s), so updating the data needs no restart.

castlemap-mcp.service is the systemd unit used in production — loopback-bound, DynamicUser, ProtectSystem=strict, with nginx terminating TLS in front. Set ExecStart to your own node path and ReadOnlyPaths/CASTLES_GEOJSON to wherever the data lives.

Provenance

Built by flightmussy with AI assistance: the concept, direction and review are mine; much of the implementation was written with Claude. The underlying data is not generated — it comes from Wikidata, and every record is traceable to its Wikidata item.

License

Code: MIT (see LICENSE). Data: CC0. Wikipedia summary text remains CC BY-SA and is attributed per record.
