Olumo Rock is one of the tourist destinations in the West African country where some indigenes of Egbaland hid during a civil war which broke out in the 19th century.
The rock served as a shelter for many of the survivors, who were said to have hidden in specific areas inside the caves located inside the rocks to evade attacks from enemies.
Some of these people eventually built small apartments inside the rocks and created places where they carried out their daily activities for about three years without getting into town.
It was not until after the war that most of these people started coming out of their hiding to see the other people who survived the brutality of that period.
