The Great Granary of Harappa
was the largest building of the Indus Valley
Civilization. It was about 45 meters long and 15
meters wide. It was meant to store food grains.
It had lines of circular brick plat forms for
pounding grain. There were barrack like quarters
for workmen. The granary also had smaller halls
and corridors. It was used to store surplus food
grains. There were two rows of granaries. Each
row had six granaries. A similar granary has
been found in Mohanjodaro. All the granaries
were built close to the river bank so that grains
could be easily transported with the help of
boats.
