A large open space or courtyard (10 meters square) is surrounded by a wall that had 13 openings, possibly for windows.
Ancient Indus Valley civilization courtyard excavations
In some neighborhoods, large courtyards were connected to numerous smaller buildings built at different levels. The pilastered wall on the left supported houses at a higher level.
A small room located at the edge of the street (in the center of the photograph) is where fourteen skeletons of so-called massacre victims were discovered.
This room in VS area was made with bricks set on edge to create a watertight floor. A small well was located in the southeast corner (top right) and circular brick depressions were set into the floor, presumably to hold pottery vessels.
