The enormous Buddhist temple of Borobudur is one of the world's most impressive temples, on par with Angkor Wat and Bagan - and is, of course, a UNESCO World Heritage Site. It was built in the 9th century, and then later abandoned at some point during the 14th century, during the decline of Buddhism in Indonesia. The walls are covered with over 1,400 narrative panels that have been methodically carved into the stones, there are 72 stupas on each level, each containing a Buddha figure, just visible through the latticework - but many of the heads have been taken by robbers throughout the years. The location is equal impressive with a mountain range one side and volcano Mt. Merapi's perfect cone in the distant. Of course Borobudur is crowded at times, but by coming early or even forking out the sunrise fee, it actually possible to enjoy this magnificent temple in relative serenity.
