Capernaum is one of the holiest places for Christians as it was here that Jesus based his ministry for three years or so.
The site contains a white synagogue from the late fourth century C.E. which was built over a black synagogue from the first century C.E.
The "traditional" house of St. Peter is located just south of the synagogue. Today a Franciscan chapel stands over the remains of several structures from the first century on including an octagonal, Byzantine church from the fifth century.
Capernaum is located on the northern shore of the Sea of Galilee, just west of the Jordan River.
