The Nalerigu Defence Wall is what has remained of the Naa Jaringa Walls in the village of Nalerigu located about 120 km south-east of Bolgatanga. The wall was constructed in the 16th century by Naa Jaringa, a powerful chief of the Mamprusi ethnic group. The wall used to surround the entire village however now only ruins remain. The wall served as protection from slave raiders and to make sure that Naa Jaringa’s name would always be remembered. It is said that the wall was made out of stones, mud, honey and milk.
