Do you know the ten tallest buildings in the world?

Man has broken his limit, and only by breaking it again and again can he create a new record again. In fact, our city skyline has always been defined by those in power at that time. In the past decades, churches have been their landmark buildings, followed by public institutions. Commercial skyscrapers are constantly reaching higher and higher.

However, when it comes to determining which buildings are the tallest, it becomes complicated. Is the roof the highest meter? What happens if the last floor is uninhabitable?

The High-rise Building and Urban Habitat Committee (CTBUH) has developed its own classification system for high-rise buildings. Lowest water level? Start measuring until the roof. Including spires, but excluding antennas, signs, flagpoles or other functional technical equipment. The system has surveyed and classified more than 3,400 buildings, most of which are over150m.

According to CTBUH, let's take a look at the relatively new 19 and 10 buildings in the world.
