West Asia

At a number of sites in southeastern Turkey, ceremonial complexes with large T-shaped megalithic orthostats, dating from the Pre-Pottery Neolithic (PPN, c. 9600–7000 cal BC), have been discovered.

At the most famous of these sites, Göbekli Tepe, parts of the oldest level (III) have been C14-dated as far back as to the mid-10th millennium BC (cal). On this level, 20 great stone circles (up to 20 meters in diameter) with standing stones up to 7 meters high have been identified. At least 5 of these circles have so far (as of 2019) been excavated. Many of the standing stones are richly ornamented with carved reliefs of "ears, boars, snakes, foxes, wildcats, aurochs, gazelle, quadruped reptiles, birds, spiders, insects, quadrupeds, scorpions" and other animals; in addition, some of the stones are carved in low profile with stylized human features (arms, hands, loincloths, but no heads).

On the younger level (II) rectangular structures with smaller megaliths have been excavated. In the surrounding area, several village sites incorporating elements similar to those of Göbekli Tepe have been identified. Four of these have Göbekli Tepe's characteristic T-shaped standing stones, though only one of them, Nevalı Çori, has so far been excavated. At Göbekli Tepe itself, no traces of habitation have so far been found, nor any trace of agriculture or cultivated plants, though bones of wild animals and traces of wild edible plants, along with many grinding stones, have been unearthed. It is thus assumed that these structures (which have been characterized as the first known ceremonial architecture) were erected by hunter-gatherers.

Göbekli Tepe's oldest structures are about 7,000 years older than the Stonehenge megaliths, although it is doubtful that any of the European megalithic traditions (see below) are derived from them.

Dolmens and standing stones have been found in large areas in other parts of West Asia starting at the Turkish border in the north of Syria close to Aleppo, southwards down to Yemen. They can be encountered in Lebanon, Syria, Iran, Israel, Jordan, and Saudi Arabia. The largest concentration can be found in southern Syria and along the Jordan Rift Valley; these are threatened with destruction. They date from the late Chalcolithic or Early Bronze Age. Megaliths have also been found on Kharg Island and Pirazmian in Iran, at Barda Balka in Iraq.

A semicircular arrangement of megaliths was found in Israel at Atlit Yam, a site that is now under the sea. It is a very early example, dating from the 7th millennium BC.

The most concentrated occurrence of dolmens in particular is in a large area on both sides of the Jordan Rift Valley, with greater predominance on the eastern side. They occur first and foremost on the Golan Heights, the Hauran, and in Jordan, which probably has the largest concentration of dolmen in West Asia. In Saudi Arabia, only very few dolmen have been identified so far in the Hejaz. They seem, however, to re-emerge in Yemen in small numbers, and thus could indicate a continuous tradition related to those of Somalia and Ethiopia.

The standing stone has a very ancient tradition in West Asia, dating back from Mesopotamian times. Although not always 'megalithic' in the true sense, they occur throughout the area and can reach 5 metres or more in some cases (such as at Ader in Jordan). This phenomenon can also be traced through many passages from the Old Testament, such as those related to Jacob, the grandson of Abraham, who poured oil over a stone that he erected after his famous dream in which angels climbed to heaven (Genesis 28:10–22). Jacob is also described as putting up stones at other occasions, whereas Moses erected twelve pillars symbolizing the tribes of Israel. The tradition of venerating standing stones continued in Nabatean times.Related phenomena, such as cupholes, rock-cut tombs and circles, also occur in West Asia.
