It is also known as ‘Vaan Irai Kal’ and ‘Krishna’s Gigantic Butterball’.
The boulder is approximately 6 meters high and 5 meters wide and weighs around 250 tons.
It stands on an approximately 1.2-meter (4 ft) base on a slope, and is said to have been at the same place for 1200 years.
The boulder is bigger and heavier than the monolithic stones of Ollantaytambo and Machu Picchu of Peru.
In 1908, then-governor of the city Arthur Havelock made an attempt to use seven elephants to move the boulder from it’s position due to safety concerns, but with no success.
A part of the boulder has eroded away, making it look like a half-spherical rock.
It is said that the Indian Tamil king ‘Raja Raja Chola‘ was inspired by the balance of this massive stone boulder and it led to the creation of never falling mud dolls called Tanjavur Bommai, which having a half-spherical base tends to come back to its original position every time one tries to make it fall.
