Another nice article on the research:
“Using computerised ballistic calculations based on finds found adjacent to the Jerusalem Municipality building, Israel Antiquities Authority archaeologist, Kfir Arbiv, has been able to identify the locations of the Roman siege engines used during the attack.
This was done by considering the local topography and the location of the Second Temple period city walls, in combination with ballistic calculations and the launching angle for the ballista stones found today within the ancient city.
As for the location of the Roman siege weapons, it appears that a significant number were placed in Cat Square, located around the centre of modern Jerusalem.“
