Architecture of Sardinia
The architecture of Sardinia reflects the history of the island and the cultures that have inhabited it since its first-known constructions in 4000 B.C. An especially distinctive element of Sardinian architecture is the presence of Nuraghes and other buildings constructed by the Nuragic civilization. == From prehistory to the Byzantine Era == Sardinia preserves many prehistoric and protohistoric constructions including underground tombs called Domus de Janas (Sardinian: House of the Fairies or House of the Witches), stone circles, dolmen, and menhir, which first appeared on the island at the time of the Ozieri.
