It wasn't until the British capture of Java in the early 19th century that Borobudur was rediscovered. Buried under jungle growth and volcanic ash, the massive structure was not fully unearthed for decades. During this time, Borobudur became a popular site for looters, who took sculptures, relief panels, statues, and images. Most notably, the Siam King Chulalongkorn literally took boatloads of artifacts, many of which are now on display in Bangkok Museum).
Restoration efforts began at the turn of the century, culminating with the master restoration plan created by the Indonesian government and UNESCO in 1975. The eight-year project cost $7,000,000. Since then, tourists have been flocking to Borobudur from all over the country and the world; it is now the most visited destination in Indonesia.
