In Oshogbo's history, before the reign of Oba Olarooye, seven rulers governed Ipole Omu. During Olarooye's rule, prolonged dry seasons brought suffering to the people, prompting him to send the chief hunter, Timehin, and his team on an expedition. They discovered River Osun and many fleeing from the Fulani Invasion settled in Osogbo. To accommodate the growing population, Olarooye and his people abandoned their old settlement, relocating to Ode-Osogbo. Olarooye built his palace at Idi-Osun, while Timehin established the Ogun shrine at Idi-Ogun. Since then, Osogbo has remained an economic center, shaped by migration and a new settlement.
Oshogbo experiences a lively transformation every August during the Osun-Osogbo Sacred Grove Festival, a spirited homage to the river goddess. The Sacred Grove stands as an ongoing place of devotion, witnessing daily, weekly, and monthly rituals. This grand festival paints the town with vibrant processions, melodic tunes, and captivating dances, drawing in enthusiasts and curious travelers from across the globe to partake in this annual spectacle.
Oshogbo is home to one of the largest brass casting industries in Nigeria. The craftsmanship is impeccable, and visitors can explore the fascinating world of brass casting in local workshops.
