5 useless border walls that barely slowed down the enemy

If the road to hell is paved with good intentions, then giant border walls must be made of the same material. For the cost, these fixed national fortifications did little good in keeping out those meant to stay on the other side.

Even the Night’s Watch didn’t see it coming.

Historically, most barrier fortifications fall well short of its designer’s expectations and these were no different: they were just the most famous ones.

1. The Great Wall of China

This series of walls and forts was actually contructed over many centuries, beginning in the third century, BCE. The Chinese originally wanted to keep out roving barbarians from the North while protecting that border from invasion. It did neither.

And Superman wasn’t around to rebuild it with his Wall Rebuilding… Vision. (Yes, someone put this in a movie.)

Originally conceived to be 3,000 miles long and anywhere from 15 to 50 high, it was the largest construction project by any civilization ever. Eventually, the Chinese expanded well beyond the wall. And even when they had to retreat, they were still overrun by the Liao and Jin people…and later, by the Great Khan.

2. The Theodosian Walls of Constantinople

These walls were also a series of fortifications built around the furthest extent of Constantinople (now Istanbul) by Emperor Theodosius II between 412-414 CE. While the three miles long, 40-foot walls were effective at keeping out medieval attackers, they weren’t so good against the new cannon technology.

And once inside… well… you know.

The walls of the city fell in 1453, breached by the Ottoman Turks after only 53 days. The Byzantine defenders knew about the technology but spurned the inventor of the siege cannon because they couldn’t afford it. He then turned around and sold it to the Ottoman Sultan.

3. The Siegfried Line

This monster fortification featured concrete walls and ceilings anywhere from 20 inches to five feet thick. It had thousands of bunkers and tens of thousands of pillboxes and tank traps. Much of the 390 mile stretch of wall, concrete, razor wire, and mines must have been a very formidable sight, after its construction between 1938 and 1940.

Also, there were “Dragon’s Teeth,” tank obstacles used to funnel troops and armor into cones of death.

What slowed down American tanks at this “West Wall” in September 1944 was a lack of gasoline, not the line itself. The truth is that after years of neglect, the wall was overgrown by vegetation. The Germans didn’t have the manpower to man the wall and it wasn’t designed to fight the newest tanks built for the war. The Americans penetrated the wall within weeks.

4. The Maginot Line

The French did not actually believe their 940-mile network of bunkers, rail lines, concrete and steel would permanently keep out invaders, they just wanted something that would allow them to mobilize an effort to repel anyone who attacks them. So they built the Maginot Line between 1929 an 1936.

This was impressive, but clearly not built in Belgium.

In the end, it didn’t even do that. The Germans attacked through Belgium, just as they did during the previous World War. And when the Nazis did advance on the Northernmost sections of the line, they took the fortifications in four days.

5. The Bar Lev Line

The Israelis built a $300 million fortification along the Suez Canal. They also knew it wouldn’t hold the Egyptians off forever if they were attacked suddenly. The Bar Lev Line was expected to hold them off for at least 24-48 hours while the IDF mounted a counter attack. You can probably guess how well it worked.

That’s why we don’t use earthworks so much anymore.

Armed with 100 water cannons, the Egyptians broke through the $300 million fortification in about two hours. The water cannons swept away the earthworks and a 53-minute artillery barrage breached other, reinforced areas of the wall.
