The mound, with a height of 15 metres and an area of about 9 hectares, is completely man-made – covering what has to be considered the earliest yet known cult architecture constructed by man, raised by intentionally burying it about 10,000 years ago. These buildings represent monumental enclosures constructed by hunter- gatherer groups during the so-called Pre-Pottery Neolithic (or in short: PPN) period after the last Ice Age – architecture even predating the invention of pottery.
