Here are the top 5 most incredible bridges, structures and tourist destinations that made history they feature amazing architecture!
5. The Millau Viaduct
This lovely bridge takes the title of tallest bridge in the world. The tallest point of the bridge measures in at a jaw-dropping 343 meters or 1,125 feet. Being a cable sustained bridge makes this construction even more impressive. This bridge has been ranked one of the most amazing feats of engineering several times over, and it took home the award for Outstanding Structure in 2006 from The International Association for Bridge and Structural Engineering. It finished its construction in 2004, and it connects Spain and France. It was meant to relieve traffic congestion on roads. The bridge is expected to stand for 120 years, and it cost 320 million euros or 348 million dollars.

4.The international space station   or the ISS is a pretty good example of why every kid wanted to be an astronaut when they were little. Although it is mostly used to study gravity and the environment of space, it is also used to study biology, physics, astronomy, meteorology, and many other scientific fields. The space station sits in low earth orbit, and it was first launched in 1998, and it is the largest artificial satellite in the world. It can even be seen from earth just by the naked eye. The space station has been inhabited by people from 17 different nations and it is an excellent example of humans working together. The station is also constantly growing with more and more parts being sent up when needed and when there are more technological advances. With funding for space exploration being slashed in a lot of nations, most notably America, this station hasn’t seen the growth that it once did.

3. Great Wall of China
The great wall of China was, of course, built with a very specific purpose in mind. The wall was one of the biggest feats of defense as well as engineering. The wall was constructed in 220 to 206 BC when it was commissioned by the first emperor of China. The wall also helped regulate trade as well as provided border control. Little of the wall as we know it today is part of the original. The wall has been rebuilt, renovated, and enhanced to the point that little of the original wall still exists. Nevertheless, it earns a place on our list because of the sheer fact that it measures in at an incredible 21,196 kilometers or 13,171 miles in length. It also one of China’s most popular tourist attractions, but despite popular opinion, it is not visible from space. A photographer captured something that looked like the wall in low orbit, but it’s been disputed if that can be used as proof that the naked eye can see it. A person would need over 7x the average eyesight of humans.

2. Great Pyramids of Giza
One of the oldest feats on our list, the pyramids still more than qualify. The great pyramid of Giza is the largest and oldest of the ancient Egyptian pyramids, and it is also the oldest wonder of the ancient world while also being the only one mainly intact. It held the title of the tallest human-made structure for more than 3800 years. It measures in at 146 meters or 481 feet. The building of the pyramid was so accurate that there is an average margin of error of about 58 millimeters. The estimated workforce to build the pyramids is an average of nearly 15,000 people and a peak of above 40,000. It’s also believed that without the use of modern tools, the pyramids took about ten years to build. Despite popular opinion, it’s recently been discovered that the pyramids weren’t built using slave labor. The team consisted of highly skilled workers instead of random people. We’re still learning more about how this structure was built thousands of years later.

1.The Large Hadron Collider
The large hadron collider is the largest and most powerful particle collider in the world as well as the biggest single machine in the world. Located in Geneva, Switzerland, the team that built it consisted of over 10,000 scientist and engineers from over 100 countries and with the collaboration of hundreds of universities and labs. The building of the monster means that we can study even more complex mysteries of physics that we would have never been able to accomplish before. Research done with this hopes to answer the questions of the fundamental laws of physics as well as the structure of time and space, quantum mechanics, and general relativity. It was built by CERN or the European Organization for Nuclear Research from 1998 to 2008. It also took a budget of 7.5 billion euros or a little or 8 billion dollars. Research has mostly been focused on finding the Higgs Boson particle that exists in theoretical physics but hasn’t been observed in the natural world.
