The largest megalithic site in all of Southeastern Asia may also be the oldest on Earth. At nearly three thousand feet above sea level, Gunung Padang spreads over a Java hilltop in a series of terraces bordered by retaining walls of stone. These are accessed by about four hundred successive andesite steps rising more than three hundred feet. The seventy-two-acre complex is covered with massive, rectangular stones of volcanic origin, known as magnetised ballast.
