Touted to be the biggest religious gathering on Earth, the city of Prayagraj is all set to witness the Mahakumbh fair which attracts devotees and travellers from across the country.
The humongous gathering often strains the rivers which the authorities try to manage by efficiently administering the fair.
The Mahakumbh fair which is held once in 12 years, holds the record for having a footfall of 120 million people in 2013.
The upcoming fair in 2025 is expected to break this record.
