Jetavana is one of the most famous Buddhist monasteries which is now part of present-day Uttar Pradesh. This monastery was gifted to Bdudhda by one of his patrons, Anathapindika. Jetavana is situated right outside the old city of Savatthi. Buddha gave the majority of his discourses and teachings in Jetavana. Out of the forty-five vassas (three-month annual retreat that Theravada practitioners observe), Buddha stayed in nineteen of those at Jetavana.
