摘要：During the war against Pisa for the dominion of Sardinian Kingdom, the Catalans established their first settlement on the island in a site until then uninhabited, originally a military camp called Bonaria. It developed rapidly and very soon had a dense population of inhabitants, emigrants from the Kingdoms of the Crown of Aragon. Alfonso's plan, heir to the Aragonese throne, was to reinforce the anti-Pisan function of Bonaria, in order to provoque an economic crisis and a subsequent withdrawal of the enemies from Castel di Cagliari. According to sources, it is possible to reconstruct the evolution of the town-planning policy of Bonaire until the conquest of Castel di Cagliari, when Alfonso decided to populate the pisan castrum and accompanied this project with a program to boost the economic activity in the port of Lapola, through a privilege system; indeed within the Catalans Castel di Cagliari carried out a mainly defensive-political and commercial role. The research offers also a new contribution of the Sardinian urban history; in fact, it analyses the project of Lapola's foundation and the systematic catalanization of life standards.
