Twenty or so miles to the east of the city of Yogyakarta, Java, is the ancient Hindu site of Prambanan, which I've written about previously. About twenty miles to the west of Yogya, on a slight rise, lies the once-lost ruins of Borobudur temple. While Prambanan is a grouping of temples, Borobudur is a massive pile of over two million pieces of grey stone. How it ever got "lost" is beyond me, but this enormous site was known only to the locals who canibalized it for their own building for a millennium. "Discovered" in the mid-1800's, it was a ravaged pile of tumbled stones. Talk about your tough jigsaw puzzles!
We stayed in the hotel adjacent to the site, so had easy access across a field to the site. The first photo shows our view from the gardens of the hotel.
