Borobudur is a Buddhist stupa and temple complex in Central Java, Indonesia dating from the 8th century, and a UNESCO World Heritage Site. This is one of world's great ancient monuments, the single largest Buddhist structure anywhere on earth.

This is the upper level of three. Inside every bell-shaped stupa is a statue of Buddha; the top has been taken off this one to reveal the content.

I thought it was crowded in 1981 but since it became a UNESCO World Heritage Site in 1991 it has become the most popular tourist attraction in modern day Indonesia and a major international attraction.
