What was the city with a tower "that reaches to the heavens" called?

Answer: Babel

People built a city and tower to make a name for themselves. It was called Babel, because there the LORD confused their language.

“That is why it is called Babel, for there the LORD confused the language of the whole world, and from that place the LORD scattered them over the face of all the earth.”— Genesis 11:9 (BSB)
