Third Military Gate and "Sigma", Istanbul

Third Military Gate and "Sigma", Istanbul

The third military gate is one of the two minor military gates that guard "the Sigma" - a "c"-shaped part of the wall, probably made to enhance the defense of the wall in that particular part. The third military gate is nowadays sealed up, but you can come and see the site from where the ancient defenders of this magnificent city stormed out to defend the walls. "The Sigma" is still a topic of discussion for historians.
