 One of the unique structures of Igbo culture was the <unk> Pyramids , at the town of <unk> , in <unk> , northern Igboland . Ten pyramidal structures were built of clay / mud . The first base section was 60 ft. in circumference and 3 ft. in height . The next stack was 45 ft. in circumference . Circular stacks continued , till it reached the top . The structures were temples for the god Ala / Uto , who was believed to reside at the top . A stick was placed at the top to represent the god 's residence . The structures were laid in groups of five parallel to each other . Because it was built of clay / mud like the <unk> of Nubia , time has taken its toll requiring periodic reconstruction .
