If you know of Da Nang at all, it's probably as the location of a major American airbase during the Vietnam War. Since then, it's become one of the country's richest cities, and with great wealth comes a great desire to showboat to your neighbors.

So if you're crossing the Cau Rong Bridge over the Han River, you'll see a giant golden dragon head rising out of the concrete. Keep going and you'll see that the arches of the bridge are actually part of the dragon's body. Reports of a massive treasure trove under the bridge are unconfirmed, but probably true.

The bridge supports six lanes of traffic, was designed by the Louis Berger Group, and oh, right -- it sprays jets of fire.

The dragon puts on a pyrotechnics show every evening at nine o'clock, and at night the bridge is lit up by over 2,500 LED lights. Because when you build a fire-breathing golden dragon into your city's infrastructure, you're not super worried about appearing ostentatious.

In one of our most beloved articles, "The 6 Most Boring Industries Ever," cement mixing easily took the number one spot. You have gray factories producing a gray material that gets driven around in gray trucks: It doesn't exactly scream "childhood wonder." And then there's this Czech company, which looks like Willy Wonka took a sudden interest in construction materials.

Zapa Concrete

The Zapa Cement Company is one of the largest and most successful companies in the Czech Republic, despite the fact that the CEO is apparently a very talented 9-year-old. Their buildings and trucks are painted in dozens of different styles, from scientific ...

... to, uh, pornographic?

While it's great to see cement and masturbation together at last, our favorite design is this gargantuan factory-cannon:

Is that ... ?

Yup, it's totally the alien from Alien. How did that get up there? It's just some bizarre coincidence, right? Or maybe God's a huge Ridley Scott fan. But wait, there's more! Here's Gizmo from Gremlins, along with one of his darker brethren:

And here's Grendizer, a character from a Japanese anime about giant robots that's crazy popular in France for no apparent reason.

The church was built in the 15th century, but of course these characters didn't exist back then (or did they?). But in 1993, the church had fallen into disrepair and needed major renovations. Stone carver Jean-Louis Boistel was assigned the task of replacing several missing gargoyles, and luckily for us, even France has giant nerds.

Stationed on the streets of the capital city, Kinshasa, are traffic lights shaped like robot policemen. Standing at more than 8 feet tall, these solar-powered robots have been incredibly effective at regulating traffic on one of the busiest streets in the city. It turns out that people are much more willing to follow the law when it's being enforced by a giant metal man in sunglasses.

It may seem like an absurd solution, but the Traffic Terminator program has been so successful that it's expanded to a second city. It helps that these things aren't just metal scarecrows -- they move like they just walked off the set of a 1950s sci-fi movie.

If that wasn't enough, the robots' eyes are functional cameras that allow them to monitor the flow of traffic and ticket speeders. We are one giant pistol and six giggling schoolgirls away from an anime premise.

The next time you're flying into Denmark, look out the window and you might spot what appears to be a gigantic paper airplane thrown by Galactus: Destroyer of Worlds.

It's actually part of a walkway at Copenhagen Airport, one of the oldest and largest airports in Europe. Each year it sees millions of tourists, businessmen, and irritating college students claiming they're there to "study abroad" when they really just want to smoke weed and rant about the evils of capitalism.

If you don't have enough of daddy's money to visit Europe for a mid-school vacation, never fear: Someone made a detailed flight simulator model of the whole airport, so you too can experience the unique sensation of landing a plane in a plane.

If this building wasn't located in Bangkok, we'd swear it's where the robot policemen go when they head home for the night.

This is actually an office tower that serves as the headquarters of the United Overseas Bank's Thailand Division. Hey, just because you work for a universally despised parasite industry, that doesn't mean you can't have a little fun! The building stands 17 stories tall, the eyes are executive suites, the eyelids are sunshades, and the giant antennae are lightning rods. At night, the eyes flash to the tune of "The Robot Symphony" by Jacques Bekaert, and that's ... not ominous or anything. Also, we're just going to go ahead and quote this out of context: "His nuts were the biggest in the world at time of development."

The building was designed by architect Sumet Jumsai after watching his son play with a toy robot, so we're sure the people of Bangkok are just happy the kid wasn't playing with a My Little Pony or something (although Fluttershy might make a pretty sweet addition to the skyline). Jumsai is definitely a man after our own heart: When asked why he built the robot, he simply responded, "Why not the robot?"

Named after the Aztec snake god, Quetzalcoatl's Nest grants its owners the most badass home address this side of Cthulhu's Court. The twisting, two-story-tall snake body is located just outside of Mexico City and houses 10 apartments that look as cozy as anything inside a gargantuan god-snake could possibly be. For all of its sinister appearances, however, Quetzalcoatl's Nest is very environmentally friendly: The only changes made to the ravine were done for safety purposes, and the facility even has its own wastewater recycling center and irrigation system.

Even cooler is the facility's main entrance, which is, of course, the snake's huge gaping maw. If you're lucky enough to snag a condo inside the ancient tribal deity, be sure to warn your friends and family beforehand: Nobody's entirely comfortable just strolling right on into what appears to be Cobra Commander's summer home.
