This paper aims to produce new insights into the complex relationship between the spatial and social dimensions of ethnic segregation in the public space of the walled city of Nicosia. The ethnic demographic of Cyprus is subject to a changing population dynamic by net in-migration, from both the EU and Third World countries, which is mainly found in the city centres. The mechanisms involved in the ways Cypriots and ethnic minorities use the public space of the city centre and the interface (or lack of it) between them lies at the heart of this paper. Building on existing research, the study focuses on a ring of public spaces which, despite their small size and the absence of any clearly defined boundaries, form a physically continuous spatial entity that is distinctly divided among different users. An attempt to account for the observed phenomenon is facilitated by the discussion of a number of relevant topics such as: the city centre as an edge condition; the entrance of users into the space through injection versus infiltration; the relationship between history and spatial adjacency; and the emergence of social phenomena from the attempts of individuals to 'make-do'.
