Mystery of The Great Granary
The Great Granary is a 'Mystery Building' at Harrapa. It is over 60 meters long! It contains six long halls which are raised above the ground by walls. Nearby the Great Granary, there is a number of circular brick platforms. Archaeologist's first thought that the building was a granary. They thought the building was built above ground level so air could keep the wheat dry. Finally, they thought the ramps were to load and unload. Though, there is no evidence of any grain! Also, the main building's platforms were built at different times. Maybe it's a palace, maybe a temple. That's a mystery yet to be solved!
