This dissertation will deal and focus on the several actions to be taken to propose a conservation, reuse, or requalification project in a particular, uncertain and difficult context of a divided city. The final aim will be the proposal of a masterplan, or better, of some scenarios for the requalification of the division area and thus for the two sides of the Cypriot capital, Nicosia, whose deeper investigation was allowed thanks to the opportunity of doing a semester abroad in the capital of Cyprus. After an analysis of other case study, namely Beirut, Jerusalem, Mostar and Gorizia, the focus will be in finding analytic tools to divided cities.
