The World's 2,400 Castles

 https://thecastlemap.com/

by marklit

7/21/2026 at 4:45:34 PM

If you submit some map, at least don't have the title contradict the content description:

"the 2,435 most significant landmarks worldwide, ordered by a fame ranking that blends Wikipedia coverage with real readership."

or someone fix the title here please to what on the app right now:

"Map of the world's great castles & fortresses" whatever that means.

Germany's Saxony alone has 700+ fortications with about 100 being touristically interesting. In the map I count like 9.

Yeah, actually a very cool idea. Hopefully somebody takes it and makes a greatly improved version, as execution is lacking here!

by deepvibrations

7/21/2026 at 6:32:21 PM

I would take it as just rounding 2,435 -> 2,400. No big deal.

by carra

7/21/2026 at 6:59:46 PM

The point is not the rounding, it is that it is not counting a total number of castles, but rather some subset of 'significant' castles

by monknomo

7/21/2026 at 9:39:33 PM

It also lists some "castles" that no longer exist, e.g., Fort Detroit, which was where downtown is and very much not extant (and not to be confused with Fort Wayne to the southwest of downtown, which does exist but isn't on the map). This is just some AI slop wasting our time.

by garciansmith

7/21/2026 at 9:59:42 PM

They are including wooden palisaded forts, of there are many more in the US and Canada than shown.

by kevin_thibedeau

7/21/2026 at 5:52:05 PM

not really castles - it includes palaces for examples and chateaus.

by Romario77

7/21/2026 at 7:26:50 PM

I find the word "castle" can be a little vague, like with Neuschwanstein Castle, which is really more of a palace. I don't think it's worth battling too much about what is or isn't a castle. I don't think you could come up with one set of castles in the world that satisfies everybody.

This is off by many degrees of magnitude for Ireland at least: https://www.reddit.com/r/dataisbeautiful/comments/1nkvqd7/oc...

by clickety_clack

7/21/2026 at 5:34:13 PM

Same for France and Spain, which is what I am familiar with. I am expecting it to be true all around.

The map of France shows maybe 100 castles? If you include castles, forts and chateaux (which it seems the map aims to do) France has around 45000 of them, including 15k medieval castles (military), an other 15k from the Renaissance period (mix of military and luxury), and 20k more recent ones (some military, many luxury type).

I know if at least 20 medieval castles within 1h of my hometown and not a single one is here.

For Spain maybe 10k to 20k castles and forts. Out of which at least 2500 genuine medieval castles (not just big houses with fortifications)

by limaoscarjuliet

7/21/2026 at 5:00:06 PM

Seems like your map lists pre-historic ring forts, not castles?

I'm not sure what the 'official' definition of a castle is, but I personally wouldn't consider a crannóg or something like Dún Aonghasa a castle. Nor would I consider a stand alone tower house a castle, although they might (along with gate lodges and great houses), sometimes be colloquially referred to as castles.

Surely a castle is a fortified building, specific to the middle ages. Wikipedia agrees - https://en.wikipedia.org/wiki/Castle

Which would put the number of Anglo-Norman castles in Ireland much lower, probably something around 100.

by dbspin

7/21/2026 at 6:19:30 PM

Yeah, in the other direction, I see at least one WWII-era "pillbox" bunker in France (part of the Marginot Line?) listed as "fortress".

It's a nice idea, but the range seems extremely broad on the one hand but very incomplete on the other hand.

by xg15

7/21/2026 at 5:33:33 PM

I like the definition where castle is a fortress where a Nobel lives. Fort is where an army lives but no Nobel leader. Palace is where a Nobel lives but it isn't expected to withstand a siege

by bluGill

7/21/2026 at 5:41:46 PM

*Noble. Alfred Nobel invented stable explosives and started a Norwegian prize for achievement in science. Nobles, however, were high ranked members of the feudal hierarchy, often passing their position on to their children.

by RugnirViking

7/21/2026 at 5:59:26 PM

Wasn’t he Swedish?

by RodGodKiller

7/21/2026 at 6:16:47 PM

Yes. All the prizes except the peace prize are awarded in Sweden. Norway was in a union with Sweden at the time the prizes were set up, but it's not definitely known why he chose the Norwegian parliament (via the Norwegian Nobel Committee) to aware the peace prize.

by vidarh

7/21/2026 at 5:25:12 PM

The map has a category for fortresses too. Which are included in its total count of "castles". So it's seems reasonable to bring them up.

by Bedon292

7/21/2026 at 5:31:22 PM

Fair, I think the map is nonsense, but also the idea of 30K castles in Ireland is clearly untrue.

by dbspin

7/21/2026 at 6:40:04 PM

In the intro paragraph of the linked Wikipedia page: “Use of the term has varied over time and, sometimes, has also been applied to structures such as hill forts”.

by clickety_clack

7/21/2026 at 4:50:57 PM

Same for Scotland - there are 3 castles within 2 km of where I live, not including a couple of really old ruined hill-forts... which I don't think is an unusual density of these things for this part of the world.

Edit: And of course there is also the huge castle 13km away across the sea sitting on its volcanic plug and very visible from here.

by arethuza

7/21/2026 at 8:06:32 PM

For England as well, assuming a conservative definition like: Norman or later, mortared stone construction with remaining walls at least 4m high, not something like a fortified farm house for a single family. If you include Iron Age hill forts, the number becomes absurd.

by tengwar2

7/21/2026 at 5:30:20 PM

Same for France, many are missing

by tgdn

7/21/2026 at 5:36:54 PM

Cool idea, horrible dataset. Its limited to things in Wikidata rather than using OSM, and it must have an article on Wikipedia in English to count so I am sure it is missing just based on that. And somehow it misses many castles (and other categories it includes) which do meet those requirements.

There is no definition of what they use to categorize anything either. And it clearly isn't applied consistently. There is a Château category and yet many things with Château in their name are tagged as castles.

by Bedon292

7/21/2026 at 10:14:28 PM

Thanks for the feedback. I will try my best to fix the dataset.

Hi thanks for the feedback and thank you Marklit to submit it here!

Thecastlemap.com is one of the websites I operate. I also operate trainrouter.com, sunshineatlas.com. and europebeachmap.com.

Honestly, I did not want to focus too much on this website due to what I thought of a market of low demand. However, there are so many critical comments. Hence, I will fix it properly and this will be one of the websites I will fully commit to.

I appreciate everything guys even if you probably do not like the website. The reason why I made the website is because I reallly like castles....

by Flightmussy

7/21/2026 at 10:16:45 PM

Please don't be detered by the less constructive comments, there are a myriad of approaches one could take and it's impossible to please everyone. Even if it has failings I think it's a great site and I'm grateful. Plus let's not forget it's delightfully free of advertising/ pushy banners to sign-up or pay!

by nmstoker

7/21/2026 at 6:20:15 PM

Nice project :3

There's a MASSIVE amount of castles missing

Just for France, the castle visible on the map -> this is not even 5%

Depending on the count it goes from 20000 castles to 45000 (just for France!)

by mrjay42

7/21/2026 at 6:09:07 PM

Clearly vibe-coded. Cool idea though. I can see what was leveraged from the Wikipedia data set.

https://en.wikipedia.org/wiki/Citadel_Hill_(Fort_George)

https://en.wikipedia.org/wiki/Georges_Island_(Nova_Scotia)

https://en.wikipedia.org/wiki/Citadelle_of_Quebec

It’s missing the extensive Napoleonic-era Western Fortifications on the opposite side of Dover from the much more famous Dover Castle.

https://en.wikipedia.org/wiki/Dover_Western_Heights

But to be fair they’re much less well known, and quite well concealed, and are partly on private land, with big fences, cameras and scary warning signs. Tourists don’t seem to be much interested in post-medieval fortifications.

by mr_toad

7/21/2026 at 5:50:36 PM

It's probably somewhat regional, as the ones in Canada seem to have pretty good tourism interest, especially when they're right inside a city like Quebec and Halifax.

But we're also very starved for true "Medieval Castles" like Europe or east Asia, so we take what we can get!

by yabones

7/21/2026 at 5:32:48 PM

Nice project, but what is "hidden" gem about Elmina castle in Ghana?

If Cape Coast Castle is described as "world renowned", then Elmina should be as well. I live in Ghana their popularity is almost evenly matched.

Also Elmina castle is the oldest and largest European building in existence in sub-Saharan Africa.

One more thing, it is kind of hard to click on specific dots when they are so clustered together. I had to zoom in a lot to see and be able to click on some of the castles I knew were there.

Palácio da Bolsa in Porto is not, at all, a castle. It was built in the XIX century as the stock market and never served defensive purposes as castles would. Not to speak about the sheer amount of misses in Portugal. This is off by a lot!

by jcfariadias

7/21/2026 at 6:42:34 PM

I had to look up Madagascar's castle: https://en.wikipedia.org/wiki/Rova_of_Antananarivo

The Rova of Antananarivo /ˈruːvə/ (Malagasy: Rovan'i Manjakamiadana [ˈruvᵊn manˌdzakəmiˈadə̥nᵊ]) is a royal palace complex (rova) in Madagascar that was the home of the sovereigns of the Kingdom of Imerina in the 17th and 18th centuries, as well as of the rulers of the Kingdom of Madagascar in the 19th century. Located in the central highland city of Antananarivo, the Rova occupies the highest point on Analamanga, formerly the highest of Antananarivo's many hills.

by Aardwolf

7/21/2026 at 7:58:56 PM

It's not very comprehensive at all, the regions I know well in France are missing almost all of the actual castles. The site lists 180ish castles in France, when it's estimated there are 45,000 castles + chateaus in reality. Of course this depends on your exact definition of castle.

I wonder if it's only scraping english language Wikipedia articles?

My understanding was always that aside from vanity castles like Craigdarroch (https://thecastle.ca) there aren't castles in North America because they're only practical in a pre-cannon world

by sharkjacobs

7/21/2026 at 9:24:14 PM

Castles became star forts, with stone/brick augmented with massive amount of earth. These were relatively effective against artillery into the 20th century.

Castles are practical against cannons but only if built with thicker walls than typical.

by the__alchemist

7/21/2026 at 5:24:37 PM

The local "castle" on the map is Fort Duquesne, which is listed as "ruins" but in fact has no ruins to visit. It says "The site of both forts is now occupied by Point State Park, where the outlines of the two forts have been laid in granite slabs" - which is true, but...there are no ruins here!

If forts count as castles, at least do Fort Pitt, which has the blockhouse functional.

Anyways - this is a fun project and it should continue!

by kinow

New Zealand was colonised long after castles had become obsolete. There are a few remains of WWII coastal fortifications here and there, but they’re now obsolete too.

The Māori built thousands of hilltop fortifications with wooden palisades (Pā), but lacking metal tools they didn’t build with stone.

by mr_toad

7/21/2026 at 5:26:46 PM

See, I'd class those as something like 'follies' or Whimsy, as they don't appear to be actual fortifications, rather forms of affectation.

That said, I'm not sure what definition or list this site uses - as others have already pointed out, there are loads of castle missing I can tell, just from a few that I've visited across Italy.

Meta commentary: this is clearly a vibe-coded frontend to a low quality "dataset" with substantial omissions.

The real value and work would be someone actually compiling and creating a high-quality castle dataset, in which case anyone could vibe-code a similar frontend to it.

Potentially a agent (swarm) could do this, if properly integrated into OSM, wikis, libraries, photographs etc. But it wouldn't be quick and would still benefit from a human-in-the-loop verifying each entry.

Nope, unless you count things like this: https://www.kryalcastle.com.au/

We just stayed in Dalhousie Castle, the oldest in Scotland. Very beautiful and well maintained, with lots of spooky history.

If you want to leave a legacy, build something out of stone.

by pizzathyme

7/21/2026 at 6:43:00 PM

I mean no, it's not.

Castle Sween was built in the 11th century (and might still not be the oldest).

Dalhousie Castle was built in 1247 and the oldest bit of the surviving castle is from the 15th century. Most of it is from the 17th century. The roof is post-2004.

The actual lesson is, if you want to leave a legacy, hope someone rebuilds it when it falls apart after you're gone.

by philipwhiuk

7/21/2026 at 9:56:31 PM

There's no need to correct. They had a lovely holiday at what they thought was the oldest castle in Scotland. Leave them to it instead of jumping in with 'actually, I've identified at least three castles older, and while we can't be certain which is the oldest fort in Scotland, we can be confident that it wasn't the one you thought you had a nice time at'

So I could name recognise the top ten, and yeah I won’t argue too hard with the list, just apart from Neuschwanstein - but the second I saw it I realised I did not know the name but “Bavarian fairy castle” clearly deserves its ranking

Immediately curious about the concentration of castles on the Ghanaian coast. Wonder what that's about.

During the height of the Triangle Trade, Europeans built a lot of forts to protect their interests along the Gold and Ivory Coasts; why these forts are considered castles by this site is beyond me (just for clarification: a castle is a fortified private residence).

Edit: I now realise that the site specifically says "Map of the world's great castles & fortresses", so I guess the site considers them fortresses, not castles. I retract my snark.

There is no taxonomy of these things you could make that will not cause some eyebrow raising choices.

It counts Clarence House in London in its top 100 as a world famous ‘palace’ - it’s a Georgian townhouse.

Age of sail trading post forts seem a relatively uncontroversial inclusion in comparison.

The title of the page is "Map of the world's great castles & fortresses". So those are latter.

Would be amazing to see which one of these are on sale.

Castles come up for sale fairly regularly in the UK. They are (generally) relatively inexpensive to buy, but ruinously expensive to renovate and maintain.

Interesting that in Canada Rideau Hall counts, but Casa Loma does not.

Invading Australia is looking pretty tempting right now.

Invading Australia in 1500s is looking pretty tempting, you mean.

Australia doesn’t have a single castle!

Who would've built them before modern Australia started to exist tho?

Château de Saint-Cloud, near Paris, reported as "renowned ruin" ??? What a joke! Only the gardens remain.

Even more ridiculous : Bastille also reported as "renowned ruin". Nothing remains. All stones have disappeared centuries ago.

There are many castles near my parents house in france. I don't see any of them? AI generated?

thinking the same here. combining the inaccurate data with the suspicious-looking sheen to the UI makes me think it was made with an LLM.

Great project! Kudos to the designer.

Might need additional datasets though -- this one is lacking. only ~10 fortresses in France? LOL

The fortress / castle distinction is quite difficult and perhaps not useful? This map classifies the Crac (Krak) des Chevaliers[0], in modern-day Syria, as a "castle" but I would argue it's really a "fortress" (and in fact, one of the best preserved ancient fortresses in the world).

Where is the castle of James Damore?

Tangential, but many of these aren't what people traditionally would think of as castles. Is there any consensus on what the "castliest of castles" is? Presumably something in the UK or Ireland or thereabouts considering that's where the popular media conception of them comes from.

Is a palace a castle? If so then there are a huge number missing in India.

Heavily lacking at least in Poland. Reeks clanker powered. I miss the times where actual hobbyists were doing stuff.

I mean, the reason why these dominate in Europe is because largely of the medieval era and a bit before that. Once gunpowder became more widely used, castles became increasingly obsolete. Nowadays they have only touristic value really or movie values, such as the castle in the movie Monty Python and the holy grail. Other than that they are just stone ruins really, some more polished than others. They have no real worth nowadays other than wonder how many resources went into building them.

Also, as others pointed out, the map is missing many castles. I also doubt the spread over China, the map only says about 7 castles in whole China? So that seems totally wrong. The definition for a castle must be incorrect, because Japan has attributed many more and that is simply objectively incorrect. Is the chinese palace classified as a castle? If not, why not? If yes then why not other palaces in China? The map is really not very good here. It should begin by a good definition of what is meant with a castle.
