Every year, all of the province's approximately 600 monkeys are invited to eat fruits and vegetables during an annual feast held in honor of Rama, a hero of the Ramayana, who, it is said, rewarded his friend and ally, Hanuman the Monkey King, with the fiefdom of what is now Lopburi. Organizers of the annual monkey buffet use more than 3,000 kg of fruits and vegetables for the festival.
