Archaeologists say they may have discovered the mines of King Solomon, one of the Bible's wealthiest figures.
According to the Journal of Archaeological Science, scientists from Tel Aviv University found evidence of "defensive measures" in Timna Valley in Israel.
They believe the fortifications exist to protect copper -- an extremely precious resource, much like oil is today.
The site was initially uncovered in 1934 and called "Slaves Hill" as it showed signs of being a slave camp in the Iron Age.
The Tel Aviv Archeologists revisited the fortifications recently, and new insights show the location was home to a sophisticated society during a time of military conflict.
"Historical accuracy of the Old Testament accounts is debated, but archaeology can no longer be used to contradict them," team leader Dr. Erez Ben-Yosef told Sci-News.
