Some archaeologists are of the opinion that the fortress was only a single tower, located at the south-east corner of the site; for example, Pierre Benoit, former professor of New Testament studies at the École Biblique, having carried out extensive archaeological studies of the site, concurs and adds that there is absolutely no support for there having been four towers.
Beberapa arkeolog berpendapat bahwa benteng itu hanya berupa satu menara, terletak di sudut tenggara situs itu; misalnya, Pierre Benoit, mantan profesor Perjanjian Baru studi di École Biblique, setelah dilakukan penelitian arkeologi ekstensif  pada situs itu, sepakat dan menambahkan bahwa sama sekali tidak ada dukungan untuk mendukung adanya empat menara.
