It is a larger stone constructed either as burial sites or commemorative memorials.
These types of structures were predominantly constructed during the Neolithic period and persisted through the Chalcolithic Age, Bronze Age, and Iron Age.
In India, they mainly belong to the Iron Age (1500 BC–500 BC), with some exceptions, such as Chalcolithic-Megalithic sites. Whereas, South India’s megalithic culture had a much larger chronological span.
The megalithic people constructed elaborate tombs. They furnished them with essential objects. They thought this practice to be necessary as they believed in the afterlife of the dead.
Their economy was based on agriculture. The megalithic people introduced tank irrigation in south India and thus brought a revolutionary change in the agricultural system.
Iron objects have been found universally in all the megalithic sites.
