The Haryana government has declared two sites of over 4,400-year-old Harappan civilisation in Bhiwani district as protected monuments and archaeological sites.
The two sites are situated at two neighbouring villages of Tighrana and Mitathal.
The Tighrana region was first inhabited by Chalcolithic agricultural communities as early as 2,400 BCE.
These early settlers (very popularly known as Sothians) lived at Chang, Mitathal, Tighrana etc. in small mud-brick houses with thatched roofs.
They used copper, bronze and stone implements as discovered in large numbers.
