A lunar-crescent-shaped stone monument that dates back around 5,000 years has been identified in Israel.

Located about 8 miles (13 kilometers) northwest of the Sea of Galilee, the structure is massive — its volume is about 14,000 cubic meters (almost 500,000 cubic feet) and it has a length of about 150 meters (492 feet), making it longer than an American football field. Pottery excavated at the structure indicates the monument dates to between 3050 B.C. and 2650 B.C., meaning it is likely older than the pyramids of Egypt. It was also built before much of Stonehengewas constructed. 

Archaeologists previously thought the structure was part of a city wall, but recent work carried out by Ido Wachtel, a doctoral student at the Hebrew University of Jerusalem, indicates there is no city beside it and that the structure is a standing monument.
