How castles get their names

Real castles are almost always named after the place they guard, not the other way round. Windsor Castle is the castle at Windsor; Harlech is the castle at Harlech. That's why historic castle names sound like town names with "Castle" bolted on. Fantasy castles break this rule constantly, naming themselves after what they do (Watch, Guard, Hold) or what their builders wanted you to feel (Dread, Storm, Iron). Both approaches work, but mixing them on one map looks like two different writers.

The words inside old castle names are worth knowing. Scottish castles often start with Dun (a fort), Kil (a church), Inver (a river mouth) or Bal (a farm). Welsh ones use Caer or Castell for a fort and Llan for a church enclosure. English towns ending in -caster or -chester grew from Roman forts, and German castles end in -burg, -stein or -fels, a fort, a stone or a rock. Building a name from these parts gives you a castle that sounds grounded in a real country.

Fantasy castle names and fortress names

The fantasy keep style joins a strong image to a job word: Stormguard, Eaglecrest, Winterwatch. Add Keep, Citadel or Bastion when you want it to sound bigger. The grim style uses the same shape with darker words, Blackspire or Bonecrag, and also produces "The Keep of the Broken Oath" style names, which are really short stories. Those suit ruins, villain lairs and anywhere a bard would sing about.

A castle's name should also tell you who holds it. A royal seat can be grand (Suncrown Palace), a border fort should be practical (Harrowgate), and a lord's manor can just be his family name with Castle after it.

Castle names with a story behind them

  • Eaglecrest KeepA high-perched fortress name; the crest tells you it sits on a ridge with a long view.
  • WinterwatchA northern border fort in one word, built to see trouble coming across the snow.
  • Suncrown PalaceGrand and bright, a royal seat rather than a military one, and a fine target for a heist.
  • Harrowgate CitadelHarrow suggests plowing or torment; either way, nobody gets through this gate easily.
  • Swanmere CastleA castle on a lake, elegant and a little soft, perfect for a court full of intrigue.
  • Stoneford HoldGuards a river crossing, which is exactly why real castles were built where they were.
  • BlackspireOne tall black tower is all a villain needs, and this name paints it.
  • Bonecrag FortressBuilt on a rock and surrounded by what is left of the people who tried to take it.
  • RavenmawMaw makes the castle sound like it eats visitors, which suits a cursed ruin.
  • The Keep of the Broken OathA name that begs the question who broke it, which gives you a plot hook for free.
  • Duskhollow KeepSits in a valley that loses the light early; quiet, old and probably haunted.
  • The Citadel of Seven BellsAn oddly specific detail makes a place memorable and gives players something to ring.
  • Dunmorran CastleDun means fort in Scottish place names, so this sounds like a real Highland stronghold.
  • Inverlorne CastleInver marks a river mouth, placing the castle where a river meets a loch or the sea.
  • Caer DerwenWelsh style: Caer for fort and derwen for oak tree, a fortress by an old oak.
  • Castell RhosRhos means moorland in Welsh, so this is a lonely castle on open, windy ground.
  • Selcaster CastleThe -caster ending hints the site was a Roman fort before anyone built a castle.
  • Castle CromwickCastle-first word order sounds older and more Irish or Scottish than the English habit.
  • Burg AdlerfelsGerman for eagle rock; exactly the sort of crag-top castle you see above the Rhine.
  • Drachenstein CastleDragon stone in German; a real-sounding name with a fantasy wink built in.
  • Kilbrannoch CastleKil points to an early church, suggesting the castle grew around a holy site.
  • Thornwick CastleAn ordinary English village name plus Castle, which is how most real castles are named.

Tips for naming a castle

  • Name the place first, then the castle. If the town below is called Ashbury, the castle is Ashbury Castle, and the map instantly makes sense.
  • Use the castle's job. Watch, Guard and Gate for border forts; Palace or Court for royal seats; Hold or Keep for a lord's stronghold.
  • Pick one country's naming parts for a region. Dun and Inver for a Scottish-style highland, Caer and Llan for a Welsh-style west, -burg and -stein for a German-style kingdom.
  • Save "The Keep of the..." names for ruins and legends. A castle that's in daily use gets shortened to a single word within a generation.
  • Avoid famous fictional castles like Winterfell, Hogwarts or Castle Greyskull. They come with baggage your players already know.
  • Say it in a sentence: "We ride for Eaglecrest at dawn." If it sounds clumsy aloud, it'll sound clumsy every session.

Questions people ask

What are good fantasy castle names?

Good fantasy castle names join an image to a job: Eaglecrest Keep, Winterwatch, Stoneford Hold, Suncrown Palace. For a villain, use darker words like Blackspire or Bonecrag. For ruins and legends, try a longer name such as the Keep of the Broken Oath.

How are real castles named?

Most real castles are named after the town, river or hill they stand on, with Castle added: Windsor Castle, Harlech Castle. Older names carry local words for a fort, such as Dun in Scotland, Caer in Wales and -burg or -stein in Germany.

What does Dun mean in castle names?

Dun comes from the Gaelic word for a fort or fortified hill, which is why it starts so many Scottish and Irish place names. A castle called Dunmorran would read to a Scottish ear as the fort of Morran, which makes it a natural fit for a highland stronghold.

Should I write Castle Ashbury or Ashbury Castle?

In English, Ashbury Castle is the usual form. Castle first, as in Castle Ashbury, sounds older and is more common in Ireland and Scotland or as a formal title. Pick one form per region of your map and keep to it.
