It is hard to tell which one of the above is true. Hence the treasure either lies hidden in the fort or it was salvaged by the Indian Government.
There is also another entirely different legend of Man Singh's treasure.
According to this legend after every conquest, Man Singh would first present the loot to Jodha Bai (Akbar's wife) before presenting it to Akbar.
Jodha Bai used to skim a portion of riches and hide it in a temple in Fatehpur Sikri.
Locals believe the temple over time was buried and the treasure still lies underneath the temple.
