 Two fortresses were constructed to defend the gorge called "Asenovo kale" and "Shishmanovo kale".Many of the names of the localities around Poibrene are connected with battles and warfare in the past such as the "Cry Mound", "Grave", "Battle Dingle", "Vatahs Ditch", "Asian Dingle" and others.During the Ottoman domination the village had a special status - the inhabitants did not pay taxes and were responsible for the security of the gorge.
