Frequented since the first decades of the twentieth century, the Poetto beach in Cagliari is one of the cornerstones of the collective imagination of citizens and tourists who visit the Sardinian capital: seven kilometres of beach, the Sella del Diavolo (a promontory with a characteristic shape), the nightlife and the summer dolce vita. The "casotti", small, colourful and unruly seasonal houses that were demolished in 1986 due to the precarious sanitary conditions, still remain engraved in the memory of the citizens of Cagliari. Since then, a series of events has profoundly changed the appearance of the beach and the seafront, each marked by important legal and urban planning consequences. In 1988 the "chioschetti" were born, refreshment services which were also seasonal, but which have become a permanent and illegal presence for almost twenty-five years. In the meantime, 2002 sees the beach nourishment put in place, a work which in the intentions of the municipal administration of the time should have repaired the damage caused by the erosion of the sea currents, but which only led to a disfigurement of the beach, until then characterized by very fine and very white sand. Starting from 2012, the year in which the photographic documentation began, the Poetto has been involved in important urban and environmental interventions, which brought legality and landscape redevelopment. "Abracadabra" is a personal study on this iconic beach. A photographic research on the altered landscape of the coast, which develops following the threads of memory, identity and time. It is a story about appearances and disappearances, changing landscapes and the consequent flux of relationships.
