The Garden Under the Walls, also known as the Garden of the Brothers Giuseppe and Vittorino Fiori, is a green space located in the historic Villanova district of Cagliari, along Viale Regina Elena. Inaugurated on 28 March 2014, the project transformed a long-neglected area beneath the Castello walls into a garden promenade. Closed to the public for many years due to ongoing construction, this green space has been reopened and returned to the city. The garden spans 500 meters in length and covers an area of 6,500 square meters. The total renovation cost was 1.8 million euros. The project focused on preserving the historical significance of the area while ensuring the safety of the Castello walls. The accessible pathway, designed to accommodate people with disabilities, features seven sculptures by renowned Sardinian artist Pinuccio Sciola, adding an artistic dimension to the space. This project successfully blends green spaces, accessibility, and culture (Refs. 1, 2, 3 & 4).
