The Osun-Osogbho sacred grove is a UNESCO world heritage site. Located on the outskirts of Osogbo, it is the last remnants of primary high forest in southern Nigeria.
It is regarded as the abode of the goddess of fertility Osun, one of the pantheon of Yoruba gods.
The landscape of the grove and its meandering river is dotted with sanctuaries and shrines, sculptures and art works in honour of Osun and other deities.
The sacred grove, which is now seen as a symbol of identity for all Yoruba people, is probably the last in Yoruba culture.
