Gish Abay is best known as the source of the Abay, or Blue Nile, also known as Felege Ghion in Ge'ez, the liturgical language of Ethiopia.
About 100 meters north of the source of Abay is the church of Gish Abay Felege Ghion Abune Zerabruk Monastery, which has been one of the most respected centers for church education over the past centuries.
