La Kalsa è un giardino. Resistenza e partecipazione alla vita urbana del centro storico di Palermo, dei ruderi di guerra e della vegetazione spontanea

Palermo is a lot of landscapes. It is a geography of exaggerated places able to generate a condition of constant wonder in those who cross it. The many souls of different peoples who have inhabited it and who still inhabit it constitute a mosaic made of very close and uncovered relationships between plants, animals, men, sea and light. This contribution aims to explore - not in an exhaustive way - some conditions of coexistence that have been observed within the open spaces of the city (in particular of its Kalsa district). They are interesting because show us how spontaneous links between different species and objects (mostly ruins of the Second World War) constitute places of unprecedented beauty and social cohesion functioning in complex urban tis- sues. In front of this evidence there is the need to establish new interpretative categories of the existing, in order to generate a taxonomy. It could identify the possible active roles that the relationships and coexistences already acting can have within the project of the city (turning them into gardens, for example) and which ones should be defused because they are harmful to the inhabitants and to nature
