Concealed within the walls of settlements along the Green Line, the border between Israel and the occupied West-Bank, is a complex history of territoriality, privatisation, and multifaceted class dynamics. Since the late 1970s, the state aimed to expand the heavily populated coastal area eastwards into the occupied Palestinian territories, granting favoured groups of individuals, developers, and entrepreneurs the ability to influence the formation of built space as a means to continuously develop and settle national frontiers. As these settlements developed, they became a physical manifestation of the relationship between the political interest to control space and the ability to form it. Discussing a socio-political and economic story from an architectural and urban history perspective, this lecture focuses on how this production of space can be seen not only as a cultural phenomenon, but also as one that is deeply entangled with geopolitical agendas.
