Some sacred places of worship in the Yoruba religion include shrines dedicated to Orishas (deities) such as Ogun, Sango, and Yemoja, as well as the Osun-Osogbo Sacred Grove in Nigeria, which is a UNESCO World Heritage Site and an important place of worship for adherents of the Yoruba religion. Sacred forests, rivers, and mountains are also considered places of spiritual significance in the Yoruba tradition.
