Abstract: The main characteristics of public space are accessibility and usability
for all citizens. However, current developments, primarily observed in
cities, suggest the loss of a clear distinction between public and private space.
Instead, urban spaces of hybrid character are emerging. Spaces with public
functions, like train stations, parks or pedestrian areas, are changing in character,
and semi-private spaces, like malls or plazas, are spreading. In order
to get a realistic view of developments this article offers a critical appraisal
of recent privatisation trends followed by a brief summary. After discussing
feasible reasons for the loss of private space the article considers potential
implications for the future of citizenship.
