Vesak day is a holy annual festival for Buddhism. Vesak is the biggest event for Borobudur locals. Borobudur is the largest Buddhist temple in the world, and ranks with Bagan in Myanmar and Angkor Wat in Cambodia as one of the great archeological sites of Southeast Asia. Borobudur remains popular for pilgrimage, with Buddhists in Indonesia celebrating Vesak Day at the monument. Borobudur is Indonesia’s single most visited tourist attraction.
