Katrinka and I just spent a week in Java, first staying four nights in Jogjakarta (or Yogyakarta) and then three nights in the countryside of Borobudur. There we visited Borobudur temple built in the ninth century, the largest Buddhist site in the world. It's got nine levels and we circumambulated each level staring with the grounds, doing the top level three times.
