- Walls have been militarily obsolete since the invention of gunpowder

This is just not true enough in just the right kind of way that it deserves mention. While obviously a castle with vertical walls loses a lot of effectiveness against cannon balls, Europe was not about to give up so easily. Fortification and European society went hand-in-hand so well that Europe simply started building different castles.

Without getting really boring about this because it's already an obnoxious digression, star forts were such a bitch to attack and design that artisans from foreign countries were brought in and professional mercenaries were hired to attack them, effectively giving rise to a middle class that weren't serfs and weren't royals. As the cost of laying siege to an effective star fort became ruinous, diplomacy and alliances replaced the feudal warfare of the Middle ages. And as diplomacy and alliances replaced feudal warfare, the star forts mostly went away.

Sorry. Carry on. I just find these sorts of things fascinating.

Unnecessary further digression in 3...2...

I also find historic fortifications fascinating, but for different reasons. One of the reasons is that I just love staring at old city maps:

I used to live in this city. Actually, I can point to the specific patch of grass on that map from 1649 where someone built a residence in the 1700s (which burned down and was rebuilt in the 1890s) that I called home. About a year ago the Dutch land registration agency created a site that's "Google Maps but with time travel"; you can pick any place in the Netherlands and browse through 200 years of maps with the slider. Here's the same city as above . What I love to do is to navigate to a place I know and to find out how it developed over the decades. How do those fortifications of yore shape the cities of today?

As you mention, at a certain point the fortifications were no longer necessary. This meant that cities could finally expand in all directions without requiring expensive new fortifications to be made. For a lot of cities, it meant that housing was built right on top of old fortification structures, completely erasing that history. Berlin and Paris, for example, had a large number of bastions but you'd be hard-pressed to find traces of that today.

Interestingly, Dutch cities have often preserved some of that old fortification structure. Instead of filling up the old moats with sand and building more housing, many cities (Amsterdam is a good example) still have their canals and original moats. This is largely because the law that legislated good fortification got abolished in 1874 coincided with the advent of city planning. The completely market-driven approach to urban growth was replaced with the first real city-wide plans. So lots of fortifications were redesigned as parks, mostly for the elite:

...or as places for those elites to build mansions. Notice the bastion-shape? Those houses are still the most expensive ones in the city.

Another thing that coincided was the advent of rail transportation. The first railway lines went to the edge of the fort and not much further. Some stations were designed but nothing particularly extravagant. The de-fortification of 1874 however, allowed the new city planners to build a much larger train station much closer to the city center. Which is why a bunch of cities like Amsterdam, Haarlem and Leiden have a train station that is built on top of or just within the old fortifications.

And if your elites are particularly rich, well, why not splurge on an awesome new train station?

So are you saying Trump should build a zigzag fence?

That's actually a super interesting fact about castle building, I'll pay more attention to that next time I'm somewhere with enough history to have had castles.

The zigzag aspect of it is a function of fortification. They're pointy like that because there's no "lee" under the turret to hide in and because everywhere you can approach it, you can be shot at from somewhere they're defended.

Obviously if you could just pound the shit out of it with cannon you'd be golden but around that fortification is a ditch where they get to kill you, then a moat, then a glacis which is angled to deflect cannon fire.

Obviously this can get iterative - moat/glacis/scarp/parapet/moat/parapet/etc until the only way either side can move is if one side starves the other out.

Trump's tax plan is going to do a lot of starving the other out.

I feel that this analogy needs more of the general of the besieging army having episodes and setting his own side's supplies on fire.

If forts count, Canada has some pretty cool ones.

Clicking around randomly, Fort Beausejour was a star shaped fort. Sadly, all that are left are some ruins.

I just finished a book on Swedish architecture 1000-1800, this unbuilt fortification plan by Erik Dahlbergh from 1680 for Landskrona I found fascinating. The plan was to make it the southern capital after the annexation of Scania.
