Yogyakarta, Central Java, Indonesia Built some 1,200 years ago, Borobudur 43km north-west of Yogyakarta is the largest surviving Buddhist monument in the world. It's also a rare remnant of a Hindu-Buddhist past in a Muslim country. Unlike most Buddhist structures, it was not designed for worship but to create a spiritual experience for its visitors through its architecture and relief carvings. The structure is striking -- it's shaped like a giant wedding cake of four square terraces topped by three circular one. On the walls are reliefs that tell the history, mythology and teachings of Buddhism. A visit here is akin to a spiritual journey; from the daily struggles in life and contemplation to final enlightenment.
