4. CCTV Tower – China Central Television Headquarters (Beijing, China)
This 44 storey skyscraper isn’t a regular skyscraper, as you can tell. It’s actually a loop of 6 different horizontal and vertical structures, that create this weird shape with a hole in the middle. It was designed by 2 European architects, and at first was considered too dangerous to be built because of the high seismic activity, but in the end the project was approved and the building was built. It’s often seen as a great example of cooperation. One of the architects who designed the building said that this building “could never have been conceived by the Chinese and could never have been built by Europeans. It is a hybrid by definition”.
