Navrongo is in Ghana, near its northern (Burkina Faso) border. It is the capital of Kassena-Nankana District – which is within the Upper East Region of Ghana. Navrongo is an important market town, known for its cathedral and its grotto. Its population in 2005 was estimated to be 25,470. The terrain is flat and the ecology is typical of the Sahel – arid grassland with occasional shrubbery.
The people of Navrongo are a mixture of Nankani speakers from Zecco in what is now Burkina Faso, and Kassena Kasem speakers from Tielebe (also in Bukina Faso). The Kassena arrived first in the area, whilst the Nankani arrived later after experiencing pressure from Mossi expansion. The two groups, though they differ linguistically, share many cultural traits.
