Where is Asia’s largest cattle fair traditionally organised?

Concept

A factual location question is answered by identifying the named event and linking it to its established venue, rather than relying only on the general fame of a city or fair.

For Indian fair questions, distinguish pilgrimage gatherings, camel fairs, and cattle or livestock fairs by their event name, state, and defining activity.

Application

The description refers to the Sonepur Mela, also called the Harihar Kshetra Mela. It is held at Sonepur in Bihar and is historically associated with extensive cattle and livestock trading.

Contrast

• Haridwar is chiefly associated with the Kumbh Mela and pilgrimage gatherings.

• Pushkar in Rajasthan is famous for its camel and livestock fair, but it is not the venue intended by this standard cattle-fair fact.

• Nashik is another Kumbh Mela venue rather than the location named by this cattle-fair description.

Cross-check and result

Matching both the event name and its state confirms the pair Sonepur Mela — Sonepur, Bihar. Therefore, the required place is Sonepur.
