In Lower Galilee, about 4 1/2 miles west of Sepphoris, is the ancient site of Yiftael. This is the best preserved Chalcolithic and Early Bronze I (3150-2850 B.C.E.) village in the Galilee. The round or elliptical houses contain a single room about 15 feet in diameter. A stone base for a wooden pillar lies in the center of each house. Next to the pillar base was often found a roughly square, flat stone with two holes. What the ancient villagers used this stone for is unknown. Pre-pottery Neolithic (8300-6300 B.C.E.) remains were also found here.
