A Second Temple Period quarry that was used to mine the stones that built the Western Wall has been discovered in Jerusalem's Sanhedria neighborhood.

The Antiquities Authority says the quarry was revealed during the excavation stages routinely carried out before the building of a new home.

"Most of the stones that were found at the site are similar in size to the smallest stones that are currently visible in the Western Wall, and therefore we assume that the stones from this quarry were used to build these structures," Dr. Gerald Finkielsztejn told the Jerusalem Post. The stones were also dated by the pottery found at the site.

This is the second such quarry discovered in the past year.
