150+ Castle, Keep, and Fortress Name Ideas for Fantasy Maps

A castle name has one job: to make a reader believe the fortress held its hill for centuries before page one. The lists below give you more than a hundred and fifty ready-to-use names for castles, keeps, fortresses, citadels, strongholds, and holds, organized into the six settings our generator builds from. Every name is original invention; none is lifted from a real castle or an existing franchise, so all of them are safe to build a novel, campaign, or game world on. Scattered lore hooks show how little it takes to turn a name into a siege. If our guide to fortress types is the grammar, this page is the vocabulary.

Highland castles

Crag-and-moor names: hard consonants, high ground, and long sightlines. These strongholds crown ridges and watch the passes, and they tend to outlast the families that raised them.

• Castle Dunmarrow, which has never opened its gates to an enemy
• The Keep of Craghollow
• Bennscar Fortress
• The Torvanian Citadel
• The Hold of Glenmorra, keyed to three converging mountain roads
• Castle Fellstrath
• The Grey Keep of Highreave
• Cairnwold Stronghold
• The Iron Citadel of Braemoor
• Castle Scarncliff, garrisoned since the first stone was laid
• The Keep of Vardenfell
• Morncrag Fortress, whose beacon has never once gone dark
• The Threnmoor Hold
• Castle Dunravel
• The High Keep of Ashkeld
• Wyndcairn Citadel

• Castle Locharn
• The Bleak Keep of Feldreth

Coastal fortresses

Salt-and-cliff names for the walls that guard a harbor mouth or a landing beach. These are the first fortifications an invasion meets and the last thing a fleet sees on the way out.

• The Fortress of Brackwater, whose walls drank the last assault dry
• Castle Saltmarch
• The Citadel of Corrowe

Forest keeps

Green-and-shadow names for the fortifications that hold a woodland road or a hidden clearing. Deep cover cuts both ways: hard to besiege, easy to surround.

• The Keep of Eldervale, raised on older, deeper foundations
• Castle Oakenmoor
• The Fortress of Briarfell

• The Citadel of Brackenmoor
• Castle Nightbriar, the last redoubt of the deep wood

Desert strongholds

Sun-and-sand names for the walls that hold a well, an oasis, or the one road that crosses the waste. Out here a fortress is only ever as strong as its cisterns.

• The Stronghold of Dustmere, whose cisterns could outlast any army
• Castle Kharvane
• The Fortress of Suncrag
• Sarrowend Citadel
• The Hold of Ashquar, warden of the only well for three days' ride

• Sethrar Citadel
• The Keep of Nabrise
• Castle Draymar, whose beacon has never once gone dark
• The Fortress of Telquar

Border holds

March-and-watch names for the fortifications strung along a contested frontier. Their whole purpose is to see trouble coming and hold long enough for word to reach the capital.

• The Hold of Wardenfell, seat of the border wardens
• Castle Marchmoor
• Rangewatch Fortress
• The Keep of Eastmarch, first to light the beacon-line

• The Citadel of Duskmarch
• Castle Highmarch, whose war banners never come down

Ruined castles

Fallen-and-haunted names for the fortifications your heroes find already broken: roofless halls, cracked curtain walls, and a story of how it came down. A good ruin name should sound like an epitaph.

• The Ruins of Grimfall, whose last garrison was never accounted for
• Castle Ashfallow, roofless for a hundred years
• The Keep of Mournvault
• The Ruins of Cindergate

• Thornruin Hold
• The Ashen Citadel of Palewrack
• The Ruins of Mossvault
• Castle Direhollow
• The Fortress of Wraithfen, that no relief column ever reached
• The Ruins of Gravemoor

Using these lists well

Treat each setting section as one region of your map, not a grab bag: three neighboring fortifications pulled from the same list will sound like they were built to hold the same terrain, which is most of what believability costs. Feel free to retitle anything here, since the root does the real work; the Keep of Craghollow promotes cleanly to a full castle or a city citadel as your history requires, a flexibility our fortress types guide explains in detail. And when you need more than a list can hold, the generator on our front page builds names in all six settings, with the structure selector keeping every fortification word honest, in unlimited batches.
