Siby is a village and rural commune in the Cercle of Kati in the Koulikoro Region of southern Mali.

The village lies 50 km southwest of the capital, Bamako, on the plain to the south of the Monts Mandingues.

The troops of Sundiata Keita had just won two battles against the Sossos at Negueboria in the Bouré and at Kangigné.

[citation needed] On the top of the mountain, an arch, from where one has a splendid sight on the surrounding plain, is dug in the rock.

According to legend, it was Kamandjan Kamara who transpierced the mountain with his sabre the day before the departure, during an evening where Balla Fasséké asked each king present if he was able to do so.
