A particular development had Romanesque architecture during the Judicates period. Starting from 1063 the Sardinian Judges (), through substantial donations, had favored the arrival to the island of monks of different orders from various regions of Italy and France. These circumstances favored in turn the arrival to the island of workers from Pisa, Lombardy, Provence and Muslim Spain, giving rise to unprecedented artistic manifestations, marked by the fusion of these experiences. The cornerstone in the evolution of Romanesque architectural forms was the basilica of San Gavino in Porto Torres. Among the most relevant examples there are the cathedrals of Sant'Antioco di Bisarcio (Ozieri), San Pietro di Sorres in Borutta, San Nicola di Ottana, the palatine chapel of Santa Maria del Regno of Ardara, the Santa Giusta Cathedral, Nostra Signora di Tergu, the Basilica di Saccargia in Codrongianos and Santa Maria di Uta and, of the 13th century, the cathedrals of Santa Maria di Monserrato (Tratalias) and San Pantaleo (Dolianova). As for military architecture, numerous castles to defend the territory were built during this period. At the beginning of the 14th century date the fortifications and towers of Cagliari, designed by Giovanni Capula. After their arrival in 1324, the Aragonese concentrated the first realizations in Cagliari; the oldest Catalan Gothic church in Sardinia is the shrine of Our Lady of Bonaria. Also in Cagliari in the same years the Aragonese chapel was built inside the cathedral. In the first half of the fifteenth century a real Gothic jewel was built, the complex of San Domenico, which included the church and the convent, almost completely destroyed during the air raids of 1943, and of which only the cloister remains. Other works were the churches of San Francesco of Stampace (of which only a part of the cloister remains), Sant'Eulalia and San Giacomo. In Alghero in the second half of the fifteenth century the construction of the church of San Francesco and in the sixteenth century of the cathedral began. Renaissance architecture, although poorly represented, includes notable examples such as the installation of the cathedral of San Nicola di Sassari (late Gothic but with a strong Renaissance influence), the church of Sant'Agostino di Cagliari (designed by Palearo Fratino), the church of Santa Caterina in Sassari (designed by Bernardoni, a pupil of Vignola). On the contrary, the Baroque architecture has found wide prominence, interesting examples are the Collegiata di Sant'Anna in Cagliari, the facade
