"Granary" or Mound F Rooms, Harappa
Individual rooms are 15 by 6 meters long, and have sleeper walls for airspace between them. At each end of the rooms are three raised platforms.
Ancient Indus Civilization "granary" excavations and materials. Note that the earlier interpretation of these constructions are Harappa and Mohenjo-daro in particular are not thought of as granaries by modern archaeologists; their purpose remains unclear.
