Krishna’s Butter Ball, a gigantic granite boulder resting on a slope in Mahabalipuram, Tamil Nadu, is one of India’s most intriguing natural wonders. Measuring around 6 meters high and 5 meters wide, and weighing an estimated 250 tons, this enormous rock has been defying gravity for centuries.
Visitors often marvel at how such a massive stone remains balanced on a smooth incline without sliding down. Scientists, historians, and travelers alike have been captivated by this phenomenon. So what is the secret behind Krishna’s Butter Ball?

The Mythological Connection
Before diving into science, it’s important to understand the cultural backdrop that gives Krishna’s Butter Ball its name.
Local legend tells us that this massive boulder is a remnant of a playful act by Lord Krishna, who loved butter as a child. According to the story, this rock represents a giant dollop of butter that Krishna dropped from the heavens.
This mythological narrative has turned the boulder into more than just a geological curiosity; it’s also seen as a divine symbol, adding to its charm for visitors.
The Scientific Explanations
While mythology gives the rock its poetic story, science provides several fascinating theories that explain its puzzling stability.
1. Center of Gravity
One of the most widely accepted explanations is the boulder’s center of gravity.
The rock’s mass is distributed in such a way that its center of gravity lies precisely over the small point where it touches the slope.
This balance ensures that gravitational forces push straight down, keeping it from tipping over despite its precarious position.
2. Surface Friction
Another key factor is friction.
Even though the boulder rests on a smooth incline, the roughness of the rock’s surface and the gentle slope together create enough friction to prevent sliding.
The enormous weight of the boulder presses it firmly into place, increasing the frictional resistance.
3. Erosion and Geological Processes
Geologists suggest that Krishna’s Butter Ball could be the result of millions of years of natural weathering and erosion.
As softer material around it wore away, this granite formation may have been left behind, eventually settling into its current balanced position.
4. Natural Equilibrium
The concept of natural equilibrium also applies. Over time, the rock may have adjusted minutely to find a stable position where all the forces acting on it are perfectly balanced.
This delicate equilibrium keeps the boulder stationary, even in the face of strong winds and minor tremors.
What I Think is the Reason Behind Krishna’s Butter Ball?
Based on everything I’ve read and observed during my visit, I believe the reason Krishna’s Butter Ball stays in place is a combination of science and nature’s precision.
The rock’s center of gravity seems perfectly aligned over its contact point on the slope, and the rough granite surface adds just enough friction to keep it steady.
At the same time, millions of years of weathering and erosion have likely shaped the boulder in such a way that it found its natural equilibrium.
Standing in front of it, you realize this isn’t just a geological coincidence – it feels like nature’s own engineering masterpiece.
Failed Attempts to Move the Boulder
The mystery of Krishna’s Butter Ball deepened during the British colonial period.
In 1908, Governor Arthur Lawley, fearing the rock might roll down and damage the town, ordered it to be moved. Seven elephants were employed for the task. Surprisingly, even with all that strength, the boulder didn’t budge an inch.
This famous failed attempt only added to the boulder’s mystical reputation and reinforced the belief that it’s immovable.
Theories That Fell Flat
Over the years, some unusual theories have surfaced.
Suggestions like magnetic properties anchoring the rock or hidden artificial supports under it have been proposed. However, there is no scientific evidence to support these claims, and they are widely dismissed by experts.
Why It Remains a Mystery
Despite the scientific explanations around gravity, friction, and geological processes, Krishna’s Butter Ball continues to be a subject of awe and speculation.
Its resistance to time, weather, and human effort leaves an air of mystery that science hasn’t fully demystified.
