During the 17th century, Cheikh Abi Nawfal el Khazen built a 2-storey tower in his territory to protect the surrounding Christian villages from Muslim Shiite attacks and to watch over his lands. Years later and after all Muslim Shiites had left Keserwan in the 18th century, Abi Nawfal's grandchildren turned the tower into a church to honor St Georges the martyr before Patriarch Youssef Dargham gave the church his blessing.

Later on, and after the church underwent some major renovation and expansion works, the Khazens of Kfardebian named it the Mar Maroun church, to honor the father of the Maronites, and it has been known since as the Mar Maroun (The Tower) Church.
