Star Fort Megapost

Thursday, 1st May 2008 by Alex

A star fort or trace italienne is a type of military fortification first introduced in Italy around the mid-fifteenth century. Traditional medieval castles, towers and ring forts had proved extremely vulnerable to increasingly mobile cannons, and star forts were introduced specifically to better defend against them.

The tiny Italian town of Palmanova was founded in 1593, and using all the military innovations of the 16th century was built in the shape of nine-pointed star. You can still see quite clearly how the shape of the ramparts allows the points of the star to defend each other. Originally a moat surrounded the town (which partially remains today), and three heavily guarded gates (1, 2, 3) were the only way in.

<br/> Palmanova, Italy (Wikipedia)

Cannons were most effective when they were fired perpendicular to the walls of the building under attack, and the star shaped design meant that to best position their weapons, attacking forces would have enter the space between the points of the star - where they would be fired on from both sides!

The judicious use of moats could further thwart the attacking forces, as demonstrated superbly here at Naarden, Netherlands.

By the late seventeenth-century star forts reached the pinnacle of their development, as shown by this complicated example in Bourtange, Netherlands, which has been fully restored to how it would have been in 1742. Here we can see that the design provides defence in depth, with tiers of ramparts that an attacker would have had to overcome to be in with a chance of taking the fort.

This ingenious design quickly became the gold standard for defensive forts, and went on to spread across Europe and the Americas:

<br/> Fort Manoel, Malta (Wikipedia)

<br/> Fort McHenry, Maryland (Wikipedia)

<br/> Fort Jay (Wikipedia) and Fort Ticonderoga (Wikipedia), New York

<br/> Castillo de San Marcos, Florida (Wikipedia)

The design even reached South Africa, where today the Castle of Good Hope can be seen right in the middle of the city! It used to be on the coast, but land reclamation allowed the city to expand around it.

In the nineteenth century the development of the exploding shell changed the nature of defensive fortifications forever, and the star fort soon became utterly obsolete. Which is why several are today used for completely different purposes - like this example in Slovakia where they now spend their time trying to keep people inside rather than out.

<br/> Leopoldov Prison, Slovakia (Wikipedia)

And finally, what is probably the world’s most famous star fort isn’t actually known for being a star fort at all - as Fort Wood is today the distinctive star-shaped pedestal underneath New York’s Statue of Liberty.

We’ve previously featured just one star fort several star forts, including Kastellet in Copenhagen, Citadel Hill in Canada, and the aforementioned Fort McHenry in Maryland. If that’s not enough, there’s a whole page about them at Wikipedia too.

    I thought, with some excitement, that this might be the longest post, by sights used, but, sadly, it was beaten to the punch by Street fight in Street View!

    But I suppose this is the most ‘unique’ sights used! Either way, great post!

    Hmmm, it would appear that the “latest sights” feature in the sidebar is better than me at finding star-forts we’ve previously featured…. *scurries off to update the post*

    I noticed that too. I guess after the first one, they realised that it was the most pointless summit imaginable.

    There all kinds of forts and castles around Portsmouth Harbour, I definitely recommend looking around and checking them out.

    This has nothing to do with forts but I saw it and thought I’d point it out.
