'Ain Ghazal is a Neolithic site located in North-Western Jordan, on the outskirts of Amman. It dates as far back as 7250 BC, and was inhabited until 5000 BC. At 15 hectares (37 ac), 'Ain Ghazal ranks as one of the largest known prehistoric settlements in the Near East.
In its prime era circa 7000 BCE, it extended over 10-15 hectares (25–37 ac) and was inhabited by ca. 3000 people (four to five times contemporary Jericho). After 6500 BC, however, the population dropped sharply to about one sixth within only a few generations, probably due to environmental degradation (Köhler-Rollefson 1992). 'Ain Ghazal started as a typical aceramic Neolithic village of modest size. It was set on terraced ground at a valley-side, and was built with rectangular mud-brick houses that accommodated a square main room and a smaller anteroom. Walls were plastered with mud on the outside, and with lime plaster inside that was renewed every few years.
'Ain Ghazal people buried some of their dead beneath the floors of their houses, others outside in the surrounding terrain. Of those buried inside, often later the head was retrieved and the skull buried in a separate shallow pit beneath the house floor. Also, many human remains have been found in what appears to be garbage pits, where domestic waste was disposed, indicating that not every deceased was ceremoniously put to rest. Why only a small, selected portion was properly buried and the majority just disposed of, remains unresolved.
'Ain Ghazal was discovered in the 1974 by developers who were building a road through the area. Excavation began in 1982, however by this time, around 600 meters (1,970 ft) of road ran through the site. Despite the damage urban expansion brought, what remained of 'Ain Ghazal provided a wealth of information and continued to do so until 1989. One of the more notable archaeological finds during these first excavations came to light in 1983. While examining a cross section of earth in a path carved out by a bulldozer, archaeologists came across the edge of a large pit 2.5 meters (8 ft) under the surface containing plaster statues. Another set of excavations, under the direction of Gary O. Rollefson and Zeidan Kafafi took place in the early 1990s. The site was included in the 2004 World Monuments Watch by the World Monuments Fund, to call attention to the threat of encroaching urban development.
