As the siege tower rose, it claimed lives of many Guge slaves.
Ancient stories tell how the slaves were beaten so mercilessly, through their organ show to their flesh.
But building a 100-meter structure of this kind would have been a near impossible engineering feat for its time.
Instead, experts believe the Ladahki siege tower was a psychological rather a physical gambit.
How long could King Khri bKra shis Grags pa lde bear to watch the daily torture and suffering of his captured subjects?
As legend has it, the last king, Khri bKra shis Grags pa lde, seeing the great suffering that his people were enduring building this wall without food and as a, died and succumbed to the pressures of construction.
He saw the great suffering that his people were undergoing.
And he had a great pity, the king of Guge, and he decided, it must have been a difficult decision, but he decided, in the end, to surrender.
According to legend, in the final hour of Guge, King Khri Kra shis Grags pa lde and his retinue made their poignant descent from summit to base, even bearing gifts of gold and silver to appease the invaders.
But the reception they received from the Ladahkis is surrounded in controversy.
In one fell swoop, the 700-year-old kingdom of Guge had been conquered.
But what happened after the king surrender is still shrouded in mystery.
