This article discusses one vector of statist control in present-day Jerusalem, a divided city that is held together primarily by the bureaucratic and military grip of the Israeli state. This vector is composed through the positioning of four architectural forms, the last three of which have, in particular, qualities of walls, but of walls that enfold. I refer to them as the 'museum-wall', the 'mall-wall', and the 'separation barrier'. These physical forms are brought into conjunction through the idea of vector, used loosely in a topological way (as distinct from topographical), in which value is carried (non-linearly) through space—that is, it is enhanced and made more powerful as it is shaped in its continuing. These walls capture and contain, folding into themselves that which they circumscribe and thereby recursively fortifying themselves.
