"BorderLine”, the first publicationin the "RIEAbooks”-series, highlights a particularly relevant site in Europe, the town and harbor of Kraljevica, just south of Rijeka, Croatia, where failing ship-building industry and pollution from a large oil-refinery threaten both the ecology and the prospects of tourism. Drawing on the results of a workshop organized, funded and conducted by RIEAeuropa in the Frankopan Castle in Kraljevica, "Borderline” presents essays and projects by leading thinkers and architects addressing the contemporary problems such tumultuous and paradoxical regions have and create within rapidly evolving European and global landscapes. The phenomenon "Borderline” is pointed out in an unparalleld way in many essays for example by Lebbeus Woods, Gabriela Seifert (member of Formalhaut Architects), Manuel Delanda (cultural philosopher), Aleksandra Wagner (sociologist and psychoanalyst), Heinz Foerster (biophysicist), Ekkehard Rehfeld (architect) and architectural projects and conceptual proposals by Lebbeus Woods, Peter Cook, Will Alsop, Per Kartredt, Masihiko Yendo, Guy Lafranchi, etc.
