Forestiere Underground Gardens Located at 5021 West Shaw Avenue in Fresno, California are an unusual manmade creation built by Baldasare Forestiere, an immigrant from Sicily, over a period of 40 years from 1906 to until his death in 1946. It is operated by members of the Forestiere family through the Forestiere Historical Center, and can be considered a spectacular and unconventional example of vernacular architecture.
