Every year, adherents and non-adherents of Osun, one of the Orisa (the traditional deities of the Yoruba people), travel from all over the world to attend the annual Osun-Osogbo festival in August. Visitors include nationals of Brazil, Cuba, Trinidad, Grenada, and other nations in the Americas with a significant Yoruba cultural heritage. Annual traditional festivities and invocations of the Osun goddess are held along the banks of the river bearing her name into which - according to Yoruba Oratory traditions - she transformed.
Ọṣun-Ọṣogbo Grove, the shrine of the annual rites of the deity and an important artistic center, was declared a World Heritage Site in 2005
