A stone structure larger than a football field in northern Israel has been identified as a 5,000 year-old monument by an Israeli archaeologist.
The 150 meter long stone structure is located about 12 kilometers northwest of the Sea of Galilee, between the towns of Parod and Shefer. Pottery excavated from the crescent-shaped monument, known locally either as Rujum en-Nabi Shua'ayb or Jethro Cairn, dates it to between 3050 and 2650 BCE, making it older then the Great Pyramid of Giza in Egypt, Fox News reported.
Though it was previously thought to be the remnants of an old city wall, Ido Wachtel, a doctoral student at the Hebrew University in Jerusalem, showed that there was no archeological evidence of a city near it, and posited that the structure is in fact a monument carrying symbolic significance.
According to Wachtel, the monument's shape, a crescent, may have been chosen to symbolize the ancient Mesopotamian moon god Sin. Wachtel also noted that an ancient town called Bet Yerah, "house of the moon god" in Hebrew, is only a day's walk from the monument - too far to act as fortifications, but just enough to possibly serve to mark the town's borders.
