context_page_description: Harappan architecture is the architecture of the Indus Valley Civilization, an ancient society of people who lived during circa 3300 BCE to 1300 BCE in the Indus Valley of modern-day India and Pakistan.
  The civilization's cities were noted for their urban planning, baked brick houses, elaborate drainage systems, water supply systems, clusters of large non-residential buildings, and new techniques in handicraft and metallurgy. Its large urban centres of Mohenjo-daro and Harappa very likely grew to containing between 30,000 and 60,000 individuals, and the civilisation itself during its florescence may have contained between one and five million individuals.
context_section_description: Mohenjo-daro has a planned layout with rectilinear buildings arranged on a grid plan. Most were built of fired and mortared brick; some incorporated sun-dried mud-brick and wooden superstructures. 
  Sites were often raised, or built on man made hills.  This could be to combat flooding in the nearby areas. Another aspect of the architecture is they often built walls around their entire cities. This could have served several different needs. Many believe that the walls were built as defensive structures, where “Large and impressive construction works can be used to intimidate potential attackers (Trigger 1990),” . It was also an obvious feature to show the city was strong and powerful by being able to divert resources and labor to make such a large structure and not focus all of their energy on survival.  This was not the only purpose for the wall, it is thought that the wall also served as protection from floods. There is also evidence of a tapering at the bottom of the wall to guide the water away from the city. 
  The city could be split into two different sections: an upper "acropolis" and a "lower town". The lower town consisted of lower valued residential building located on the eastern side of the city, while the upper acropolis would be on the western side of the city which contained of the higher value buildings and public buildings. The acropolis was a “parallelogram that was 400–500 yards north-south and 200–300 yards east-west” It was also thought that the acropolis area would be built on the highest part of the mound in the city showing the importance and status of the area was much higher than the rest of the area. Another feature which suggests the acropolis is of higher importance is that the fortifications around the area where bigger and stronger than those around the rest of the city.
