UNESCO has a world heritage list which may have monuments or sites of interest to WLM: http://whc.unesco.org/en/statesparties/gh

Also the Ghana Museums and Monuments Board (GMMB) has a list which has served as the reference for our WLM so far. 

In the event where there's a monument or site on the UNESCO list which is not on the GMMB list can we visit anyway? 

We are not bound by local lists are we?
