    The dynamics of land occupation in Conakry is approached from the angle of both the colonial authorities and the local dwellers. The former took upon themselves the power of allocating plots and strove to enforce a colonial urban pattern. The latter succeeded in partly appropriating the town in spite of the minutiae of the law. As the urban area extended, Conakry was divided into three zones according to an ordinance of 1905. Although the third zone was officially termed 'native', there were no ethnic or national criteria.
