Prayagraj is transforming into a massive temporary city to host the Maha Kumbh, the world's largest religious gathering, expected to draw over 40 crore pilgrims. The preparations include extensive infrastructure development, including 160,000 tents, 150,000 toilets, and a 1,250-km pipeline network. The event, starting on January 13, will culminate on February 26, bringing together millions of devotees for the holy dip at the confluence of the Ganga, Yamuna, and Saraswati rivers.
