Samatzai lies on the slopes of Monte Titas, on the eastern border of Medio Campidano province. Having always been an agricultural hub, as of the end of the 20th century, its focus also turned to industry upon the establishment of lime and cement processing facilities, being amongst the largest in Italy, exploiting the lime quarries that are a great resource for the area. In a town of 1,700 inhabitants, Samassi is a ‘gateway’ between the Campidano plain and the ‘gentle’ undulations of the historic territory of Trexenta. Trexentino inspired the traditional structure, development and architecture of the town, with large houses of a farming matrix, spit over two floors surrounded by extensive courtyards, ‘nestled’ within a historic town with an artistic appearance. They overlook streets around the 15th-century parish church of San Giovanni Battista, which houses ancient wooden statues of saints and a splendid 16th-century solid silver cross.
