CITIES OF THE INDUS VALLEY CIVILIZATION 69
Pakistan to the Gulf of Khambat (Cambray) in India, and, heading inland, along the final 1,600km
of the river and its tributaries. Geographical conditions vary throughout this area. The northern
sector lies largely in the Punjab, a well-watered region, thanks to adequate rainfall and to its rivers.
The best-known site here is Harappa. Rakhigarhi, a site of similarly large size, lies at the eastern
edge of the Punjab, 350km from Harappa, the north-eastern limit of the Indus Valley Civilization.
Directly south of the Punjab is Cholistan, a drier region. Its major Harappan site is Ganweriwala,
an unexcavated city that lay alongside the Saraswati River. Further south still is Sind, a hot, rainless
area whose geography and climate recall southern Iraq. Mohenjo-Daro, 570km south of Harappa,
is the major site of this region, and indeed the most extensively excavated and best known of all
Harappan sites. The last of the geographical regions is the coastal zone along the Arabian Sea, a
largely inhospitable area, rocky and with limited fresh water supplies. Despite this inhospitable
environment, the important Harappan city of Dholavira was established here, on a small island
(the region has since filled with silt, however; Figure 4.1 shows the modern coastline).
The five sites mentioned above, the largest known Harappan sites, have been identified as the
major regional centers. Excavations at smaller sites and surface surveys have given additional
information about Indus Valley urbanism and rural settlements. The five major sites are dis-
tributed at fairly regular intervals from north-east to south. Each would have controlled a large
hinterland, with its agricultural production and natural resources. In addition, Dholavira must
have profited from its maritime location. What we do not know is whether these five cities, surely
preeminent in their respective regions, and indeed all cities and towns, were joined together in a
single state, or whether, as in Sumer, the city-state was the basic unit of government.
We shall focus here on Mohenjo-Daro, with a brief look at Lothal, a smaller city in the extreme
south-east of the Harappan region, to see how the layout and architectural features of a provin-
cial town compare with those of a metropolis.
MOHENJO-DARO
Mohenjo-Daro is the largest known city of the Indus Valley Civilization, with an inhabited area
now estimated, thanks to surface survey work, at over 250ha. The city proper, covering an area of
ca. 80ha as explored through excavations, is a well-planned city located today some 5km from the
Indus River. It is not known whether the river flowed closer to the town in Harappan times.
Mohenjo-Daro is also the most extensively explored Harappan city, thanks to excavations
conducted first in 1921 by R. D. Banarji, then from 1922 to 1927 by Sir John Marshall, the first
director of antiquities of British India, with E. J. H. Mackay continuing until 1931. Work has
continued sporadically since the Second World War by British, American, and German teams.
Struck by major floods in antiquity on at least three occasions, the city still faces danger today.
Through capillary action, the ancient brick buildings suck water from deep in the ground. The
salts left behind after the water evaporates corrode the buildings. Effective protection against the
rapid disintegration of Harappan architecture has yet to be found.
Although the city wall has not yet come to light, Marshall assumed Mohenjo-Daro was forti-
fied, as has been attested at Harappa and at other, smaller sites. The wall would lie buried beneath
the unexcavated alluvial deposits in the surrounding plain. The city plan consists of two main
sectors, a higher part in the west, misleadingly called the “citadel” (Figure 4.2), and a lower, larger
town to the east. The placement of important public buildings in the north-west, characteristic of
the major Harappan sites, recalls Mesopotamian practice: one thinks of the ziggurat and temenos
at Ur, sited in the north-west of that city. In contrast with Mesopotamia, however, the lower town
