How High Was the Tower of Babel?

The story of the Tower of Babel in Genesis 11 has long fascinated readers of the Bible. This ancient structure was built by the united people of the world soon after the Flood. Their intent was to construct a tower that would “reach to the heavens” (Gen 11:4). But God was displeased with their efforts and confused their languages, scattering them across the earth.

Centuries later, the Tower of Babel remains a symbol of human arrogance and defiance against God. Its image still captures our imagination today. But one question lingers unanswered: just how high was the Tower of Babel?

While Scripture does not provide exact dimensions, analysis of the biblical text provides some clues. By understanding the engineering capabilities of ancient societies, the logistics of such a monumental project, and the theological significance of “reaching heaven,” we can make reasoned estimates of the tower’s height.

Join me as we explore this question and unravel the mysteries of Babel!

Key Takeaways:

  • The Tower of Babel was likely between 300-650 feet tall based on analysis of Genesis 11 and ancient ziggurat designs.
  • Given the post-Flood population size, the Tower was ambitious but not impossible to construct with mudbrick technology.
  • The phrase “with its top in the heavens” implies an arrogance of purpose more than sheer height.
  • God’s scattering of languages emphasizes that human pride ultimately fails to achieve its agenda.
How High Was the Tower of Babel?

The People United to Build

The account of the Tower of Babel is found in Genesis 11:1-9:

Now the whole earth had one language and one speech. 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. Then they said to one another, “Come, let us make bricks and bake them thoroughly.” They had brick for stone, and they had asphalt for mortar. And they said, “Come, let us build ourselves a city, and a tower whose top is in the heavens; let us make a name for ourselves, lest we be scattered abroad over the face of the whole earth.”

But the Lord came down to see the city and the tower which the sons of men had built. And the Lord said, “Indeed the people are one and they all have one language, and this is what they begin to do; now nothing that they propose to do will be withheld from them. Come, let Us go down and there confuse their language, that they may not understand one another’s speech.” So the Lord scattered them abroad from there over the face of all the earth, and they ceased building the city. Therefore its name is called Babel, because there the Lord confused the language of all the earth; and from there the Lord scattered them abroad over the face of all the earth. NKJV

This passage places the Tower of Babel’s construction soon after the Flood narrative of Genesis 6-9. Noah’s family repopulated the earth after the Flood. At this point in Genesis 10-11, the whole earth has “one language and one speech” (11:1).

Seeking to establish the first urban civilization, the people journey east and settle on the plain of Shinar. With abundant bitumen deposits, they are able to make durable mudbricks to build their city and monumental tower. The tower reaches high into the sky as a focal point of their ambitions.

But God is displeased with this endeavor. He confuses their languages and scatters them over the earth. The name “Babel” represents this confusion of tongues (11:9).

What Motivated the Builders?

Understanding the motivations behind the Tower of Babel gives us insight into its massive scale. The builders had several key motives:

Technological Capability – With one language, the technological knowledge of all people was pooled together. They sought to build the tallest structure ever conceived to display their engineering prowess.

Monument to Human Achievement – By saying “let us make a name for ourselves,” the people wanted to create a lasting monument that would give them renown throughout history.

Cohesiveness Against God’s Will – Banding together to build a city and tower was an act of human cohesiveness apart from God’s call to “fill the earth” after the Flood (Gen 9:1).

Reaching Heaven Itself – The ultimate arrogance was architectural ambition to build to the heavens, the realm of God himself. This may imply building a “stairway to heaven” or a portal to the divine.

The Tower of Babel represents humanity’s first attempt to exalt itself using united technology to construct an architectural wonder. Yet paradoxically, the end result was the confusion of languages and the scattering they were trying to avoid.

Engineering Feasibility: Mudbrick Ziggurats

To estimate the tower’s potential height, we must explore the engineering capabilities of the ancient world. Archaeological and textual evidence points to mudbrick “ziggurats” as the most likely design model for the Tower of Babel.

Ziggurats were stepped pyramidal temples built by ancient Mesopotamian civilizations out of mudbricks. The most prominent example is the Great Ziggurat of Ur constructed circa 2100 BC. This structure was built with an estimated 720,000 mudbricks, stood about 70 feet high, and had a square base measuring 210 by 150 feet.

This was certainly a monumental architectural feat. Yet the well-organized workforce that constructed Ur’s ziggurat was likely a fraction of the post-Flood population united together on the plain of Shinar. Conservative estimates put the global population at that time in the range of tens of thousands, but possibly over 100,000.

With a larger workforce marshalled together, a mudbrick tower up to seven times the height of the Great Ziggurat of Ur was potentially feasible. Such a structure would stand around 500 feet tall. Other experts propose the Tower of Babel was between 300-600 feet in height based on typical ziggurat proportions.

This range agrees with the Tower of Babel account. The people intended to build high into the sky, but well short of astronomical proportions. God dispersed them by language confusion, not because they came close to actually reaching heaven. A monumental but achievable height in the 300-650 foot range concords better with the text than vastly exaggerated heights of miles high.

Phraseology Points to Arrogance

Another clue about the Tower’s height comes from analyzing key phrases in Genesis 11. Verse 4 says the people built the tower “with its top in the heavens.” Some imagine this implies an astronomical tower tens of miles high.

But in Hebrew “in the heavens” is a metaphorical expression referring to the realm where God dwells. The phrase parallels later verses saying God had to “come down” to see the city and tower (11:5). Heaven is where God resides, not an actual physical location.

The inscription on the Ishtar Gate in Babylon used similar imagery of raising the gate’s height “to the sky.” This did not imply an attempt to build into earth orbit! Rather it was reverential language to exalt the gate’s imposing height over mere mortals.

In the same way, the Tower of Babel text points to the builder’s lofty ambitions and arrogance. They wanted to build the tallest tower yet, one that figuratively reached heaven itself to exalt human achievement. The narrative emphasizes the people’s defiance, not astronomical dimensions.

God’s Intervention Halts Construction

Given the time-scale and plausibility of the project, one wonders why God intervened so swiftly rather than let the Tower reach completion?

Several factors shed light on this question:

No Limit to Human Ambition – Once finished, the success of the Tower would have only fueled further audacious projects flaunting God’s will. Better to intervene early.

United Power of the Post-Flood World – God disrupted humanity’s unity to prevent unrestrained evil (Gen 11:6). The project exhibited the potential dangers of unchecked ambition.

Confusion as Mercy to Redirect – By confusing language and dispersing the populace, God showed mercy to curb human self-destruction. Scattering humanity was ultimately for their good.

So while architects could feasibly build the Tower to its intended height, God judged the people’s defiance, not their technology. The half-finished tower stood as a reminder that human arrogance fails to achieve its agenda when confronted by the Lord and his purposes.

Lessons for Today

While we no longer build towers of mudbrick, the lessons from Babel still resonate today:

  • Technological Ability Does Not Imply Wisdom – Just because we can build something does not mean we should. Wisdom still comes from above.
  • True Unity Comes from God – Human power when unified apart from God brings judgment, not utopia. The Church’s unity is through the Spirit, not man’s schemes.
  • All Ambition Must Be Checked by Humility – The loftiest human plans are as dust before the Lord. We must build our lives upon Christ, not our achievements.

The proud tower of Babel lay abandoned, a cautionary tale for all generations. Let us renounce arrogance and instead build upon the Cornerstone of Christ, who alone bridges heaven and earth. All other ground is sinking sand.


The Tower of Babel remains a symbol of human ambition and pride. But Scripture guides us to walk humbly with our God, not exalt our own names. By God’s grace, the confusion of earthly languages foreshadows the eternal unity bought by Christ at the Cross. There the dividing wall of hostility was torn down as people from every tribe and tongue become citizens of heaven through faith in Jesus (Eph 2:14-22).

While we do not know the Tower of Babel’s exact height, we do know humanity cannot reach heaven without the incarnation of Jesus which made a way. He alone turns Babel’s destruction into construction, and its scattering into gathering. The true Stairway to Heaven is not built with bricks but shaped from a Cross. May we make that blessed Name our tower today.
