The imagination of modern architects is increasingly bold. They carry more and more high-risk ideas, but in practice these works are still solid.
1. Life circle, China : The construction is mainly for tourists, with the top of the observation area. The ring looks more impressive at night thanks to 10,000 colorful bulbs.
2. La Grande Arche de la Défense, France : This Puteaux (Parisian suburb) building has a unique architecture in the form of a super cube, atop a spacious conference room and observatory.
3. Arecibo Observatory, Puerto Rico : Arecibo is an amazing giant observatory. Ordinary people do not have the opportunity to admire the sparkling starry sky from there, but can stand by and photograph the National Center for Astronomy and the National Electrolysis (NAIC).
4. The Giant Turnbuckle Without Mind, China : The Chinese are very creative when they successfully build the ferris wheel without the mind being extremely impressed. Each swing chamber has Wi-Fi to share photos taken from a height equivalent to a 48-story building.
5. Vidraru Hydropower Dam, Romania : Vidraru Dam is the place where people stand in the middle of their heart. Visitors can stand on top and look down, or take advantage of the height to bungee jump.
6. Shard House, England : 72-floor Shard skyscraper, including offices and apartments. At the top is Britain's highest observatory with spectacular views over the capital.
7. Maeslantkering, Netherlands : Maeslantkering works extremely well, protecting the Netherlands from hurricanes. The barrier acts as a door: it closes when the stream of water needs to stop, and opens when the weather is nice.
8. Hoover Dam, USA : Hoover Dam is an amazingly large structure, located near the city of Las Vegas (Nevada). This is also a popular tourist destination, many visitors visit.
9. Khan Shatyr Entertainment Center, Kazakhstan : Khan Shatyr is proof that ordinary things can become great. This is just a shopping mall in the city of Astana, but also the largest tent in the world.
10. Bridge to the bottom of glass, China : This is also the largest bridge in the world, located in Zhangjiajie, Hunan Province. The bridge is nearly 430 meters long, 6 meters wide and hangs over a canyon higher than 300 meters. During the inauguration ceremony, the bridge builder demonstrated sustainability by using a 5-kg hammer to hit the floor and drive past.
11. Bagger 288 Excavator, Germany : Bagger 288 is the world's largest excavator, weighing 13,500 tonnes and requiring up to 4 people for maintenance.
12. Traffic junction Judge Harry Pregerson, USA : The traffic junction in Los Angeles is four-storey and lane hard to count.
13. Shimao Wonderland Intercontinental Hotel, China : This is the newest hotel in Shanghai. Construction architects decided to make use of the abandoned quarry to create a 328-room hotel, even some under water.
