On the outskirts of the city of Kaolack, this blue mosque stands. Alone in the vast Savannah, I found it unexpected. It's the mosque of the "Medina baye" where Caliph General of the Tidjanes Family "Niassenes" is buried. Kaolack is 200 kilometres from Dakar and is the third largest city of Senegal. It's known as the peanut capital.
