A massive baked brick revetment wall [329] surrounds the solid mud-brick foundation platform [50] of the "granary" that measures approximately 51 meters north-south and 41 meters east-west.
Overview looking north of excavations at the southeast corner of the "granary" structure undertaken in 1999 (Trench 1C). The higher east-west running walls in the left of the image and the ruined structures in the right of the image all post-date
The high mound at Harappa (Mound AB) is surrounded by a massive mud brick city wall with large square ramparts. One of these eroding ramparts is visible through the underbrush that now covers the site.
One relatively successful low cost techniques used to combat the destructive nature of salts in the fired bricks is to cover the walls with a thick layer of mud and straw plaster and to spray them with clay slurry.
Deep digging at the southeast corner of the "granary" revealed an earlier building [wall 330] constructed along the same east-west alignment. This structure could have been built as early as the beginning of Period 3B, ca. 2450 BC.
Detail view of a hollow area that would originally have held a wooden beam bonded into the baked brick structure. In the background is a wall remnant from the later rebuilding of the "granary".
Hollow baked brick buttresses were later built up against the original "granary" structure on top of a shallow mud-brick platform [400] that itself overlies the mud-brick platform of the original "granary". Below these platforms is baked brick wall
