town, Osun state, southwestern Nigeria. It lies 6 miles (10 km) north of the Iwo station on the Lagos-Kano railway and at the intersection of roads from Ibadan, Oyo, and Ogbomosho, on a low hill at the edge of savanna and forest. Founded in the 16th or 17th century, it became the capital of the Yoruba kingdom of Iwo. The former ruler of the Iwo kingdom, the oluwo ("king"), whose palace now incorporates a modern building and the local government offices, still retains important social and traditional functions and is an adviser to the local government. Within the town, many of the traditional Yoruba compounds with their rectangular courtyards have been replaced with single-story and multi-story houses.
