Working alone during his spare time and using only hand tools, Baldasare Forestiere spent some 40 years sculpting this unique underground complex of underground rooms, passages, and gardens that ramble throughout a ten-acre parcel. This place includes a network of almost 100 underground rooms, niches, courts, patios, and passageways, an underground garden home, arches and stonework patterned after the catacombs of Ancient Rome, and a chapel and chapel garden, all adorned with a unique variety of trees.
