Graffiti brings Benin's walls to life with treasures from the past

Twenty-six local and international graffiti artists are participating in the creation of a mural representing the history and culture of Benin.

It stretches for more than a kilometre along a wall in Cotonou, Benin's main city.

Their goal is to create the world's largest mural as part of a festival under the theme of "Benin New".
