The exhibition grew out of a project started in 2016 by Alessandro Rosas for the 100th anniversary of the beginning of land reclamation and was later supported by Livio Mura, Marco Pani, Giuseppe Murgia, Gesuino Loi, and Giampaolo Salaris. The study group put together the exhibition set up in 2018 in Terralba High School. Making use of original documents, pictures and illustrations, he describes nearly a century of local history intertwined with national history: from the mid-19th century to the years of the administrations of mayors Severino Lay and Emilio Cuccu. Exposes malaria issues in an area sprinkled with swamps and unhealthy ponds. It follows the path traced by Mayor Felice Porcella’s land reclamation idea, starting with the reclamation of the Sa Ussa marsh, and then describes the stages of its integral implementation through the work of the Sardinian Land Reclamation Company, with the positive and negative implications for the inhabitants of the area and the settlers who came from the mainland in the land appoderament. The exhibition, without parochialism, highlights the actions of the technicians and politicians who contributed to the realization of the land reclamation, with an eye toward the faces of those who toiled in the works: wheelbarrow drivers, terrazzo workers, laborers, bricklayers, women and children, united by the need and dignity of labor.
