Kartal County has fertile soil as a settlement area, the climate is very available, the groundwater menbaa waters are too much to be underestimated, It is a very dazzling district with its historical and cultural riches that is famous for Ayazma and has a natural wonder like the balcony of the world.

In 718, when Caliph Yazid (Kostantinapolis) ruled Istanbul, Kartaluna remained very close TO BIYENIA. The ships occupied the STYROS ports and brought them to the Eagle Harbor.

Kartaly, which has been learned to be a inhabited region since ancient times, has not been found to be based on the region about its history before the Byzantine period. However, in 1080-1083, the Seljuk Sultan Suleyman SHAH took the whole Anatolia by Pendik, Pendik, After the conquest of the eagle and Maltepe, a treaty was made in 1084 by determining the Dragos Tea border between this monarch and the Byzantine emperor of the time, and the Suleiman SHAH committed not to go outside this frontier.
