Buildings and streets were aligned along a north-south and east-west grid with minor variations introduced as new buildings were constructed. The corbeled arch in the background was built to cover a street drain, but was eventually blocked as the cross streets were filled with debris. See also First Street of Mohenjo-daro: Revisited.

"One of the finds from the former room  consisted of fragments of a pierced lattice of alabaster which presumably filled the windows or ventilators at the top of the wall. Perforated screens with geometric patterns have been met with before in Kushan and Gupta buildings. It is now patent that perforated lattices were known and employed in the Indus valley in the prehistoric period," (Marshall, Mohenjo-daro, Vol. 1, 1931, p. 219).

The great bath at Mohenjo-daro at dawn and in context. Surrounded by a brick colonnade, it measures approximately 12 meters north-south and 7 meters wide, with a maximum depth of 2.4 meters. In the background is a massive brick structure with narrow passages that was first identified as a hammam or hot-air bath, and later as the state "granary," but this is not certain. See also The Great Bath of Mohanjo-daro B.
Drawing of the Interior of Hall 76, House XIII, VS Area [of Mohenjo-daro], one of 28 rooms in a well-preserved building. "There is nothing that we know of in prehistoric Egypt or Mesopotamia or anywhere else in western Asia to compare with the well-built baths and commodious houses of the citizens of Mohenjodaro" wrote John Marshall. "One of the finds from this [room] consisted of fragments of a pierced lattice of alabaster which presumably filled the windows or ventilators at the top of the wall" (Marshall, Mohenjo-daro Vol. 1, pgs. vi, 219).

The pre-Indus civilization or so-called Ravi phase around 3000 BCE at Harappa yielded hand-formed mudbricks. Here, we can see the bricks very obviously lack uniformity in size and shape. There is a remarkable difference between these bricks and those from later periods such as those seen in the Mohenjo-daro Well and Platform. Other artifacts from this period include Ravi Phase Jewelry and the Pedestal Vessel.
"House 13 in the VS Area [of Mohenjo-daro] has a more elaborate plan . . . On its ground floor are four fair-sized courts, ten smaller rooms, three staircases, a porter's lodge, and a well-chamber. The front is towards First Street, and here there are three entrances side by side, the principal one of which is plainly the middle, since this is the only one provided with a porter's lodge.
Excavations at the "Granary," Harappa, Trenches 41 exposed new facts about this most puzzling of structures. Built apparently at one time, and more than once reconstructed on the foundations of a previous structure, there is absolutely no sign of grain in the rooms or hollow areas between them.
Harappa Mound AB Center with the great drain looking out over Punjab. Harappa was first excavated in 1872 by Alexander Cunningham, the original Director General of the Archaeological Survey of India. Although he named the mounds and found a seal and other implements after digging a handful of trenches, he was in search of a Buddhist city and did not realize that he had come upon a Bronze Age civilization that would push back Indian history 2,000 years.
"The Great Bath, which I have reserved to the last, was part of what appears to have been a vast hydropathic [water therapeutic] establishment and the most imposing of all the remains unearthed at Mohenjo-daro. Its plan is simple: in the centre, an open quadrangle with verandahs on its four sides, and at the back of three of the verandahs various galleries and rooms; on the south, a long allery with a small chamber in each corner; on the east, a single range of small chambers, including one with a well (no 16); on the north, a group of several halls and fair-sized rooms.
