Koro
Koro lies in the Mahou country, among the wooded hills north of Touba. Local tradition attributes its foundation to the Muslim scholar and pilgrim El-Hadj Moussa Bakayoko, remembered as the ancestor of the village. His descendants held the chieftaincy and became known as teachers of the Quran. A spring near Koro is associated with the founder in local tradition: it is said to have appeared after his prayers for water, and its stream was named Yirima, or hope.
