Of the most well known and threatened forms of rock art in Nigeria, the Ikom Monoliths rank high, comprising more than 300 upright, carved stones in Cross River State in Southern Nigeria. Varying in height from one to two metres, many of the monoliths are grouped in circles facing each other.
Oral histories of the region attribute the monoliths to the earliest residents of the area. The monoliths were included in the 2008 World Monuments Fund Watch List of heritage at risk due to the many threats they face.
There are also rock paintings in Birnin-Kudu in the North, as well as rock gongs scattered through the Northern regions.
