Nicosia, the capital of Cyprus (specifically, its city center) is essentially a giant star fort. The fortification walls are visible from a satellite view:

I think quite few cities in Europe either has some remnants of a star fort solution in their city plan, or a regular star fort.

In Sweden the central part of the city of Gothenburg still has parts of the star fort left:

And the castle of Landskrona has multiple layers of star fort shaped moats and walls.

Fun fact: the base of the Statue of Liberty is a star fort named "Fort Wood" [1]

I had noticed the design and had assumed it was an example of military fashion leading civilian fashion. Thanks


This quick video[1] is where I heard it, it has some other fun facts about the development of liberty island.

Not an expert, but I think these are forts rather than castles. I would describe a castle as the stronghold of a noble, with a form that evolved from iron age hillforts and progressed to the great citadels and their massive towers in the 13th and 14th centuries CE, just before the development of effective artillery rendered them obsolete. Forts on the other hand are rather more an expression of centralized state power and a professional standing military. I didn't look at the dates on all of the depicted forts but I would expect them to be 17th to early 19th century CE.


From the intro

>Historians enjoy debating the scope of the word, but usually accept a castle to be the private fortified residence of a monarch or nobleman. This definition excludes fortresses, which were not homes, and also fortified towns, which were public defences rather than private residences. Taking a little licence we can extend the definition to buildings that might not technically qualify under this definition


Great page. Gee, I wish I'd read that before I read Tristram Shandy. Ravelins, hornwork, glacis etc etc get a lot of mentions from Tristram's fortification-obsessed Uncle Toby. Somehow the joke never gets old, even not knowing what they are.


Did you read Tristram Shandy to the end? I read the first 400 pages and then I gave up. And up till this moment, I'm the only person I knew who got that far.


My wife and I spent about two months driving around europe living in a "caravan/camping car/vonmobile" (small, class-B-ish RV) and had the opportunity to stay in both Carcassonne and Neuf-Brisach.

Neuf-Brisach is an examplar star-fort, with a beautiful, calm, country feel to it.

There is a lot to be said for the design of European towns compared to those in the US.

If you are planning to go to the Yucatan over the winter, a quick trip to Valladolid will give you an easy impression.

The closest I've seen in the US is downtown Charlottesville, VA.

Curious if anyone here has found anything else in the US with a similar, car-free town center with mixed-use zoning.


What was the effectiveness of these forts? They look quite beautiful, to the point that I'm starting to wonder if it's a case of form over function. I get that the 'legs' of the star are supposed to A. Cover the other 'legs' at close quarters, and B. Create an angled surface for shot to bounce off.


> What was the effectiveness of these forts?

Very, until firepower significantly increased and powerful long range direct hits with piercing high explosive shells as well as ballistic shots (mortar, long range artillery) would just render the defence moot. From the article:

> Fortifications of this type continued to be effective while the attackers were armed only with cannons, where the majority of the damage inflicted was caused by momentum from the impact of solid shot. While only low explosives such as black powder were available, explosive shells were largely ineffective against such fortifications. The development of mortars, high explosives, and the consequent large increase in the destructive power of explosive shells. Plunging fire rendered the intricate geometry of such fortifications irrelevant. Warfare was to become more mobile

You can see this in WW1 (e.g battle of Verdun), where battlefields and front lines are very spread out and mobile[0], and key points like forts[1] are out of town, have much simpler geometry, and are dug deep to protect from artillery. Also, growing use of reinforced concrete.

Trivia: there was a level on C&C 3 (GDI Mission 10, Sarajevo) that I remember playing and as the map unfolded I saw that this was actually sort of a Vauban fort!

Fortified buildings of that era tended to be very functional, though I agree they can also be quite beautiful in shape.

One advantage of the angular bastion shape is that the triangular point does not allow for a dead zone created by circular bastions, where enemy troops can hide at the base of the wall and undermine it while concealed from most defensive fire by the bastion itself.

Normally the bastions are not just an outward triangular point, but angle back inwards on the curtain wall side as well. This would allow defenders to bring enfilading fire along the curtain wall should the attackers get that close, without being subject to direct fire from attackers further out.

Combined with the presence of a wide ditch with a glacis to the outer side and the thicker and sloped lower walls on the inner side, this made any approach to the main curtain wall, either to undermine it or to scale it, extremely difficult and dangerous for the attackers.

In addition to the angular bastions, star forts typically featured separate ravelins. These also served a number of useful functions, not least providing a relatively safe forward firing position that was protected from the front but left exposed on the curtain wall side in the event that the position was overrun and its defenders retreated. Even if they fell, their shape and position would force enemy forces to divide before reaching the main wall, and they also provided some additional protection against incoming cannon fire for the curtain wall behind, helped by being set on a different angle as you mentioned.

These tactical advantages remained relevant for quite a long period in military history, from the first star forts in the 15th century until around the 18th. They rapidly faded after that, however, as the introduction of indirect fire weapons like mortars and high explosive shells rendered the intricately shaped defensive fortifications obsolete.


Interesting choice of words: "the triangular point does not allow for a dead zone" In one sense you are right, in another you are precisely wrong. Blind spot perhaps?

Thank you for your input though :)

James Burke covered this a bit in episode 9 of Connections (about 4 minutes in):

Fascinating! Castle of Good Hope is another example that I don't see listed here: https://en.wikipedia.org/wiki/Castle_of_Good_Hope#/media/Fil.... Thought of it as soon as I heard the title but never knew it was a trend or such a practical design.


I notice they left off the most historic fort in my area.

Fort Monroe is a 7 pointed star fort at the mouth of the Chesapeake Bay.

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


I don't know what kind of people run this place but everything in my post is the same as all the others.

Some kind of inferiority complex at work. This place seems full of bullies. Facts are inconvenient huh.

Could be racists here as Fort Monroe accepted any slaves who could make it there.

It is also the largest stone fort in the US.

Maybe moderators should read a history book instead of thread bullying.


What bullying are you talking about?


There's a whole belt of those around Antwerp (at least the moats usually remain).

This zooms to just a few of them:

In case you're interested in their original placement:

The is yet another belt that loops from Bornem to Putte as well!

For people in the UK, Star Castle in the Scilly Isles is worth a visit http://www.castlesfortsbattles.co.uk/south_west/star_castle....



There's one in Tilbury, just outside London:

But there's not much else in Tilbury, so i've never been.
