This article is the first to present a study on the wagar, a sacred wooden sculpture kept by Somali women. This study explores the wagar and its significance as a sacred medium within fertility rituals and the religious syncretism in which such indigenous and non/pre-Islamic practice is appropriated and applied for reproduction purposes. The wagar seems to denote a Cushitic symbol of belief in sacred trees within Somali society. The article further explores the potential link between the wagar and the Sky-God Waaq, adhered to by the Cushitic people of the Horn both before and during the practice of Christianity and Islam. The author suggests that the religious centre of Saint Aw-Barkhadle, located in the twelfth-century Islamic ruined townwhich was a major pre-Islamic ritual and burial site according to recent archaeological work-may be linked with the practices of the pre-Islamic religion of Waaq. The article suggests the wagar and phallic gravestones discovered at Aw-Barkhadle and in other parts of the Horn of Africa may be part of Sky-God belief, with an ideology rooted in fertility. Along with traditional archaeological methods, the article also uses the knowledge-centred approach, taking into account local knowledge, oral history and folklore to explore this region's past. The study of the wagar and the shrine of AwBarkhadle contributes to the archaeology of religion and to historical archaeology in the Horn of Africa.Résumé Cet article constitue la première étude sur le 'Wagar', une sculpture sur bois sacré gardée par les femmes somaliennes. Cette recherche étudie le Wagar et sa signification en tant que véhicule sacré dans les rites de fécondité ainsi que le syncrétisme religieux dans lequel une pratique indigène et non/préislamique est opportune et appliquée à des fins de reproduction. Le Wagar semble désigner un symbole couchitique de croyances aux arbres sacrés au sein de la société somalienne. Ainsi, cet article explore le lien potentiel entre le Wagar et le couchitique Dieu du Ciel -appelé Waaq, obéis par les gens de la Corne avant et après le Christianisme et l'Islam. L'auteur suggère que le centre religieux de Saint Aw-Barkhadle, situé dans la ville en ruine du douzième siècle, soit attaché aux pratiques des religions préislamique du Waaq, le Dieu Afr Archaeol Rev (2015) 32:93-109
