The Indus Valley Civilization (IVC) was a Bronze
Age civilization (3300–1300 BCE) located in the
western region of South Asia, and spread over
what are now Pakistan, Northwest India, and
Excavations first conducted in 1921-22, in the
ancient cities of Harappa and Mohenjo Daro,
both now in Pakistan.
Believed to be created by the Dravidians.
• The Indus city was made of mud-brick buildings.
It had walls and roads.
• Water was very important to Indus people, so
the builders started by digging wells, and laying
• Most Indus people, perhaps 9 out of 10 people
were farmers and traders.
Mohenjo-Daro is divided into two section
• Smaller in area but highly developed.
• Large in area but less developed than citadel.
At the western end of the
site is an area known as the
Citadel. This area of the city
was built on top of a mound
of bricks almost 12 metres
high. A large staircase ran
up the side of this mound.
Citadel area may have been
used for public gatherings,
religious activities or
The "great bath" is without doubt the earliest
public water tank in the ancient world.
Finely fitted bricks laid on edge with gypsum
plaster and the side walls.
Most scholars agree that this tank would have
been used for special religious functions where
water was used to purify the bathers.
In 1950, Sir Mortimer Wheeler identified one large
building in Mohenjo-Daro as a "Great Granary".
Certain wall-divisions in its massive wooden
superstructure appeared to be grain storage-bays,
complete with air-ducts to dry the grain.
Granary is adjacent to the Great Bath.
The "Lower Town" is made up of numerous
lower mounds that lie to the east and may
represent multiple walled neighborhoods.
The Lower Town is organized on a grid system
with four avenues running from north to south
and four running from east to west. The
avenues are several meters wide and have
drains running down the middle or side of the
Features of Houses in Lower Town
Most of the homes are made of baked bricks
in a standard size of 28 x 14 x 7 meters.
The remains of stairways, seems to suggest
that many of the buildings had two storeys.
The houses were cool inside. Thick walls kept
people cool in the heat of summer.
Walls were covered with mud plaster. It is not
clear if people painted the walls.
The structure of the houses has one or more
toilets or toilet connected to a centralized

Over 700 public and private wells have been
found at Mohenjo-Daro.
Indus Valley cities lived by trade. Farmers
brought food into the cities. Trade goods
included terracotta pots, beads, gold and silver,
