The Stone of the Pregnant Woman (Hajjar al-Hibla) is one of the largest monoliths ever quarried. Situated in Baalbek, Lebanon, within the vicinity of the Baalbek temple complex, the stone is an exemplar of Roman engineering. It measures approximately 20.31 meters in length, 4.34 meters in width, and 4.5 meters in height, and is estimated to weigh around 1,000 tons. Its origin dates back to antiquity, specifically to the period of Roman rule when the stone was cut for use in the construction of the gigantic Jupiter temple of the Baalbek triad. However, it was never fully separated from the bedrock or moved to its intended location, leaving the task it was destined for uncompleted. The name 'Stone of the Pregnant Woman' has multiple theories regarding its origin, with one legend suggesting that the monolith's sheer size could only be explained by attributing its creation to a pregnant woman who possessed unearthly strength. The site remains a fascinating attraction, with visitors marveling at the scale and pondering the ancient constructors' capabilities.
