The Ikom monoliths are a series of volcanic-stone monoliths of unknown age ( based on two C14 datings , somewhere between 200 and 1850 AD). They are between 0.3 and 1.8 metres (1 and 6 feet) high, and are laid out in some 30 circles located around Alok in the Ikom area of Cross River State. The monoliths are phallic and some feature stylized faces as well as decorative patterns and inscriptions. Exposure to extreme weather conditions have put these monoliths at risk of erosion and deterioration. They were recently added to the World Monuments Fund's list of sites in danger and is being considered for inclusion onto UNESCO's World Heritage Site list.
