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 truly great ancient monuments, the single largest Buddhist structure anywhere on earth, and few who visit fail to be taken by both the scale of place, and the remarkable attention to detail that went into the construction. Set as it is in the heart of the verdant Kedu Plain, the backdrop of mighty active volcanoes only enhances the sense of awe and drama.
There is no definite written record of who built Borobudur or why it was built. It was likely founded as a religious site in the 8th century at the peak of the Sailendra dynasty in central Java. The construction is thought to have taken a period of 75 years, and completed in about 825 AD.
