India has many such tourist places where the treasure of kings and emperors is said to be hidden. One such place is Son Bhandar caves.
During the reign of Bimbisara, the Magadha empire had a huge treasure, the value of which was difficult to estimate.
When king's son Ajatashatru usurped the throne of Magadha and imprisoned the king, the Bimbisara's wife hid the treasure at Rajgir in Bihar.
Son Bhandar Caves are also located in Rajgir, which is said to be the entry point to reach the treasure.
King cut down a mountain and built these caves, as he had a fear that one day his son might ruin his kingdom in greed for treasure.
Many rulers made numerous attempts to steal the treasure with all their might, but they could not succeed.
The British Govt also tried to break the cave's wall with cannonballs but failed to do so.
