قاقون: انقاض جامع القرية المغتصبة

So far as I can tell this is Crusader work Caco. It is a rectangular donjon characteristic of the smaller works of poor knights. It exhibits a double, barreled vault on the lower story whilst the roof of the remnant upper story would have been supported by masonry columns similar to Burj al-Ahmar (the Crusader Castrum Rubrum).
