Olumo Rock is one of many tourist destinations in the West African country where some indigenes of Egbaland hid throughout a civil war which broke out in the 19th century. The rock served as a protection for most of the survivors, who have been said to have hidden in specific areas within the caves located within the rocks to evade attacks from enemies. Some of those people eventually built small apartments within the rocks and created places where they carried out their activities for around 36 months without stepping into town.
