Explores the difficult relationship between water and the European City; focuses on Venice, Antwerp, and Copenhagen In an urban condition where frontiers have been torn down and cities have become never-ending, the historical and visual limits that used to define urban areas are now hard to read. For example, the conventional borders such as the limit between city and country do not exist anymore. Only natural physical limits remain, for example, between land and sea. In these conditions, where the border is basically an abstract element, the question is asked about what happens when it is designed or when it is decided to work specifically on the border spaces and their physical limits, with their obvious identification problems. On the basis of these ideas, the study has focused on three important cities: Copenhagen and its fixed link (Oresund bridge); Venice and its MOSE project; and Antwerp with its PROAP project along the quays. 600 colour
