| c. 3000 | The 1st Λ STONEHENGE V begun in Wiltshire (not with big stones). The surrounding circular earth bank and ditch have been dated c.3100BC. First a circular ditch is dug some 1,050 feet in circumference, 4 1/2 to 6 feet deep and 12 feet wide, to supply the chalk soil for a bank which was thus built up along the inner side of the ditch. This alone requires 28,000 man-hours work, using red-deer antlers for picks etc. for shovels. The bank is 320 feet diameter and at least 6 feet high (some say 20 feet), with a causeway entrance on the northeast. Only a few stones are used in Stage I, a couple at the causeway entrance and perhaps the 4 Station Stones. 53 post holes are in the causeway entrance. "Heel stone" suggests sun worship. Deposits containing human bone date from 3000 BC. |

An "Altar Stone" is added, the entrance is widened and a new axis alignment made or astronomical sightings. The Sarsen Circle has 30 uprights and lintels, weighing up to 45 tons.
