Top Missing - Africa  30
A couple of questions.
In the "fast moving" posts of the last few days I might have missed something but there are a number of what seemed like good suggestions which seem to have disappeared without any discussion? Was that because no one else supported them? They all seem to have potential merit to me for any African "missing" list (though how they measure up in "World terms" is another matter.)
Benin Iya (Nigeria) C https://en.wikipedia.org/wiki/Walls_of_Benin

I don't remember any discussion about Ganvié Stilt houses which have got included above
We have been to Ganvié - https://en.wikipedia.org/wiki/Ganvie
and didn't consider it a very edifying experience or site - (see my review https://www.worldheritagesite.org/tentative/Site+Lacustre+de+Ganvi
In general it has become very big and contains a lot of modern concrete development.
Ghana has an alternative "Stilt Village" on its T List - Nzulezo (Ghana) https://en.wikipedia.org/wiki/Nzulezo
. We haven't been there but, from the Wiki description it would appear to be better preserved??
Fouta Djallon (Guinea) . Most African nominations nowadays seem to be Cultural Landscapes so I am reluctant to suggest yet another!! We have a few in our latest list of course. When Guinea was on my "to visit list" (It has undergone a lot of political and medical problems in recent years of course and I will probably never get there now!!) visiting this area was always going to be a target. Beyond the traditional villages and scenery this Wiki article identifies another aspect which would be likely to "go down well" with ICOMOS/IUCN/UNESCO - namely its "Biointensive Agriculture" . "Sometime in the late 18th century, the Fulɓe in Fouta Djallonke developed a type of biointensive agriculture, probably out of necessity, since the conquered indigenous women were taken into the households of their Islamic overlords whose livestock became their responsibility. Combining animal husbandry and sedentary agriculture into an efficient system of agropastoralism required a new way of organizing daily life. Livestock, which included horses and cattle, ate more and produced more waste than what the indigenous farmers were accustomed.

Another traditional CL which possibly merits consideration is the Baffut Chefferie in Cameroun (Unlike Fouta Djallon this one IS on the T List)- https://fr.wikipedia.org/wiki/Chefferie_de_Bafut
