Deep in the forest beside the Osun River, strange and beautiful sculptures rise among the trees: twisting figures, giant faces and shrines shaped like living forms. The Osun-Osogbo Sacred Grove, on the edge of Osogbo in south-western Nigeria, is dedicated to Osun, the Yoruba goddess of the river. It is one of the last surviving sacred forests in Yorubaland and a UNESCO World Heritage Site.
Osun, the grove and Susanne Wenger
Osun is a Yoruba orisha associated with fertility, love, healing and fresh water. The Osun River flows through the grove. The grove covers dense forest with shrines, sanctuaries and sculptures. It was once one of many sacred groves in Yoruba towns, most of which disappeared with urban growth. Susanne Wenger, an Austrian artist, came to Nigeria in 1950 and settled in Osogbo. She became a priestess of Yoruba religion and dedicated her life to protecting the grove.
Wenger worked with local artists in what became known as the New Sacred Art movement, creating sculptures and restoring shrines. Their work blended Yoruba spirituality with modern artistic forms.
UNESCO, the festival and threats
In 2005, the grove was inscribed as a UNESCO World Heritage Site, recognising its cultural and natural value. The annual Osun-Osogbo festival, usually in August, draws worshippers and tourists. A votary maiden, the Arugba, carries a calabash of offerings to the river. Susanne Wenger, known locally as Adunni Olorisha, died in Osogbo in 2009 at the age of 93.
Osogbo also became known for an art movement in the 1960s, with artists such as Twins Seven-Seven and Jimoh Buraimoh. The grove faces threats from urban development, pollution and illegal mining upstream. Visitors can walk through the grove with guides who explain its shrines and sculptures.
The Ataoja and pilgrims
The traditional ruler of Osogbo, the Ataoja, plays a central role in the festival and in the rites connected to the grove. According to tradition, Osun helped the town’s founders, and the bond between the ruler and the goddess is renewed each year. Worshippers of Osun travel from across Nigeria and the diaspora, including Brazil and Cuba, where Yoruba religion survives in forms such as Candomblé and Santería.
Most of Yorubaland’s sacred forests have vanished. The Osun grove survived because an Austrian artist and her Nigerian collaborators refused to let it go.
