These beehive dome huts show advances from original wicker-leaf domes of Congo.
The dome's square base and linear spacing in village shows population pressure of sedentarism (they are part-nomads), the domes are of sun-dried mud brick (from clod of mud/sod of soil & papyrus sedge roots excluding the edible rhyzomes). They probably have small cool cellars. The doorways and rect. doors are derived from earlier small oval entry ways, possibly due to allowing domestic animals inside during storms or raids (see Sharha of Oman with cattle domes).
