What is the significance of the Kartik Mela at Prayagraj?

The Kartik Mela is a month-long fair held at the Triveni Sangam in Prayagraj throughout the Kartik month, culminating on Kartik Purnima. Pilgrims camp on the sandbanks of the Sangam for the entire month, performing daily sacred baths, pujas, and kirtans. The final day — Kartik Purnima — sees the largest congregation of the month, with hundreds of thousands of devotees taking the concluding sacred bath.
