The Children’s Health Resort in Krvavica, Croatia, is a legendary complex from the 1960s located on the Adriatic coast. Gradually left to decay since the early 2000s, it is a masterpiece of modernist architecture designed by Rikard Marasović. This book recounts the history of a place and the real and parallel lives of a building originally intended for the treatment of children with respiratory diseases. It compiles interdisciplinary research but also reflects on citizens’ initiatives for the protection and revitalisation of the building. This is a story of the loss of social memory and transformation of personal recollections caused by radical social changes, and the consequences of these processes.
