Kalibangan

A field in Rajasthan still shows furrow marks from a plough dragged across it nearly 5,000 years ago. It is often called the world’s oldest ploughed field, though the more careful claim is: the earliest one yet found in the Indian subcontinent.

Kalibangan

Home to the subcontinent’s earliest known ploughed field and seven fire altars

Location

HanumangarhRajasthan, on the Ghaggar

Excavated

1960sBy the ASI

Name Means

“Black Bangles”From terracotta finds

Two Cultural Phases

• Pre-Harappan phase: mud-brick fortifications, tandoor-like ovens.
• Pottery from this phase resembles the Sothi-Siswal culture.
• Harappan phase: a fortified citadel plus a fortified lower town.
• The lower town’s streets form a chessboard-style grid pattern.

Landmark Finds

• The subcontinent’s earliest known ploughed agricultural field.
• Crisscross furrows at right angles suggest multi-cropping.
• A row of seven ritual fire altars was found on the citadel.
• A nearby pit held animal bones, hinting at animal sacrifice.

A Site with Two Layers

Kalibangan spans two eras. Its Pre-Harappan layer predates the mature Indus cities, while its Harappan layer shows full urban planning.

The Field, the Altars, and Two Cultural Phases Need to Know

• Kalibangan sits in Rajasthan’s Hanumangarh district, on the now-dry Ghaggar River. Some archaeologists link the Ghaggar to the legendary Sarasvati river, though that identification is itself debated.
• The name means “Black Bangles,” from terracotta bangle fragments scattered across the mound’s surface.
• The site shows two cultural phases: an earlier Pre-Harappan phase, and a later mature Harappan phase with a fortified citadel and a separate fortified lower town.
• Kalibangan holds the earliest ploughed field yet found anywhere in the Indian subcontinent, dated to before roughly 2800 BCE. It is often called the world’s earliest, though that global claim is harder to prove.
• The Archaeological Survey of India excavated the site over nine seasons, from 1960-61 to 1969-70, led by B.B. Lal.

Furrows, Rituals, and a Vanished River Good to Know

• The ploughed field shows two sets of furrows, set at right angles. One set runs east-west, spaced about 10 cm apart. The other runs north-south, spaced about 1.9 metres apart.
• That pattern points to intercropping: a taller crop grown in the wide rows, a shorter one in the narrow rows. Farmers in the region still use a similar method today.
• A row of seven clay-lined pits, generally read as ritual fire altars, was found on the site’s citadel. This reading is the standard interpretation, though it remains an interpretation of the evidence, not direct proof of ritual use.
• A nearby brick-lined pit held cattle bones and antlers, suggesting possible animal sacrifice alongside the altars.
• The Harappan-phase lower town used a chessboard-style street grid, matching the planning seen at other mature Harappan cities. For the wider civilisation these sites belonged to, see AncHist0004 — Harappan Civilisation: Sites and Discovery.

What an Earthquake and a Cylinder Seal Reveal Great to Know

• Evidence at Kalibangan points to an earthquake around 2600 BCE, which destroyed the last Pre-Harappan structural phase. Displaced walls and ground cracks support this reading. Some archaeologists have called it among the earliest such events recorded anywhere, though that claim should be read as an interpretation rather than settled fact.
• Harappans resettled the site after the disruption. It was finally abandoned as the Ghaggar dried up, cutting off the water supply that had sustained it.
• Kalibangan yielded a rare cylinder seal, K-65, showing two warriors spearing each other while a goddess figure looks on. This narrative scene is unlike the small square seals typical of most Harappan sites.
• One of the humped-bull (zebu) seal motifs common across the wider civilisation was also found here. For more on what these seal animals reveal, see AncHist0100 — Animals of the Indus Valley Civilization.
• The fire altars’ seven-pit layout has been compared to the seven Vedic dhishnya hearths used in later Soma sacrifices. Historians treat this as a noted parallel worth studying, not proof of a direct historical link.
• For how daily life, trade, and eventual decline played out across the wider civilisation Kalibangan belonged to, see AncHist0005 — Harappan Civilisation: Life, Economy and Decline.
