Should Kumasi be included? As I understand it all the sites for "Asante Traditional Buildings" are N/NE of the city of Kumasi itself let alone in what could be considered the "Old Centre"? Paul might have been there - Ghana is a West African state I haven't yet visited, only "planned" to do so! The list of sites is given as "Abetifi, Abirim, Akokoanbong, Asawase, Asenmaso, Bogyease, Darkwa Jachie, (A) dwenase, Kentenkrono, Patakro (2), Obomeng, Saaman."
The fact that none appeared to be within Kumasi was a significant "planning factor" requiring transport to get to them from the city.
