Borobudur, Java

Built between 750 and 850 CE, Borobudur was later abandoned for reasons unknown. Borobudur, the world's largest Buddhist temple, was subsequently hidden under layers of volcanic ash and jungle growth for centuries. Rediscovered in the 19th century during English occupation of the island, it has since become a highlight of visiting central Java, especially at sunrise.

Borobudur's history of surviving a bombing and several earthquakes means that security is ever-present at this UNESCO-designated Heritage Site.
