On Eyo Day, the main highway in the heart of the city (from the end of Carter Bridge to Tinubu Square) is closed to traffic, allowing for procession from Idumota to the Iga Idunganran palace.
The festival takes place whenever occasion and tradition demand, though it is usually held as part of the final burial rites of a highly regarded chief in the king's court.
[8] Among the Yorubas, the indigenous religions have largely lost the greater majority of their traditional followers to Christianity and Islam.
In his book Nigerian Festivals, travel writer and culture reporter Pelu Awofeso notes: A full week before the festival[9] (always a Sunday), the ‘senior’ eyo group, the Adimu (identified by a black, broad-rimmed hat), goes public with a staff.
Each of the four other Eyo groups — Laba (Red), Oniko (yellow), Ologede (Green) and Agere (Purple) — take their turns in that order from Monday to Thursday.
