The historic center of Sini is characterized by a massive architecture that is identified in the materials of stone and unfired earth in which the various Peasant Houses still present in the country are made. Most are of the Front and Back Court type accessed by large historic wooden portals that open onto paving made of “impedrau,” an ancient dry-laying technique of perfectly preserved basalt pebbles. Several examples of such houses are preserved, all of which have undergone typological restoration whose basalt and sandstone masonry recalls the volcanic origin of the Giara at the foot of which the village stands. Some of these houses still retain well-distributed spaces of past occupations: the granary, the private oil mill, the stables. These include the present “Casa contadina” owned by the Cau Sisters, the adjacent Casa Serra, and “Casa di Zia Bibiana” in Cagliari Street.
In the Casa contadina there is still the old oil mill with a trailing millstone for oil as well as tools for working the land.
There is also the shoemaker’s room with old tools, the trade of the father of the current owners.
In both houses the “impedrau” flooring is perfectly preserved.
“Aunt Bibiana’s House” is the arrival point of the bride and groom in the reproduction of Sa Coja Antiga held on April 25.
