Bariyarpur was a town and Village Development Committee in Bara District but now it is converted into municipality in the Narayani Zone of south-eastern Nepal. At the time of the 2001 Nepal census it had a population of 10000 persons residing in 1250 individual households.[2]
Every five years, the Gadhimai festival is held in the temple of Bariyapur. The event involves the world's largest sacrifice of animals - including rats, buffaloes, pigs, goats, chicken and pigeons - with the goal of pleasing Gadhimai, a Hindu goddess of power.[3]
