The Tower of Babel was most likely the very first pyramid and was never completed. It was built in the area of what is now known as Iraq.
Genesis 11:1-9 KJV
1 And the whole earth was of one language, and of one speech.
2 And it came to pass, as they journeyed from the east, that they found a plain in the land of Shinar; and they dwelt there.
3 And they said one to another, Go to, let us make brick, and burn them thoroughly. And they had brick for stone, and slime had they for mortar.
4 And they said, Go to, let us build us a city, and a tower, whose top may reach unto heaven; and let us make us a name, lest we be scattered abroad upon the face of the whole earth.
5 And the LORD came down to see the city and the tower, which the children of men builded.
6 And the LORD said, Behold, the people is one, and they have all one language; and this they begin to do: and now nothing will be restrained from them, which they have imagined to do.
7 Go to, let us go down, and there confound their language, that they may not understand one another’s speech.
8 So the LORD scattered them abroad from thence upon the face of all the earth: and they left off to build the city.
9 Therefore is the name of it called Babel; because the LORD did there confound the language of all the earth: and from thence did the LORD scatter them abroad upon the face of all the earth.
“It has a solid central tower, one furlong square, with a second erected on top of it and then a third, and so on up to eight. All eight towers can be climbed by a spiral way running around the outside, and about halfway up there are seats for those who make the journey to rest on.” – Herodotus, the ‘Father of History’ between 484 – 424 BC
And they began to build, and in the fourth week they made brick with fire, and the bricks served them for stone, and the clay with which they cemented them together was asphalt which comes out of the sea, and out of the fountains of water in the land of Shinar. And they built it: forty and three years were they building it; its breadth was 203 bricks, and the height [of a brick] was the third of one; its height amounted to 5433 cubits and 2 palms, and [the extent of one wall was] thirteen stades [and of the other thirty stades]. (Jubilees 10:20-21, Charles’ 1913 translation)
