In the 19th century, Dutch occupiers of Indonesia found a massive ancient ruin deep in the jungles of Java. What they discovered was the complex of Borobudur, a gigantic structure built with nearly 2 million cubic feet (55,000 m³) of stones. The temple has nearly 2,700 relief panels and 504 Buddha statues.
Until today, no one knows for sure when and why it was built, nor the reason for its complete abandonment hundreds of years ago. Some scholars believe that Borobudur is actually a giant textbook of Buddhism, as its bas reliefs tell the story of the life of Buddha and the principles of his teachings. To "read," a pilgrim must make his way through nine platforms and walk a distance of over 2 miles.
