Kursi, on the eastern shore of the Sea of Galilee, is traditionally identified as the "country of the Gerasenes/Gadarenes" where Jesus cast demons into a herd of pigs (Mark 5:1-20 and parallels). By the Byzantine period the site had become a major pilgrimage destination marked by a large monastery and church.
Archaeology
Excavations in 1971-1974 revealed the largest Byzantine-period monastery complex yet found in Israel — a 5th-century basilica church with mosaic floors, a baptistry, and monks' quarters. The identification of Kursi with the Gospel's "country of the Gadarenes/Gerasenes/Gergesenes" is scholarly-debated: the Gospel manuscripts themselves disagree on the place name, and "Gergesa"/Kursi became the favored harmonizing identification only from the Byzantine period onward.

At Kursi, Jesus crossed the lake for one tormented man everyone else avoided — who is the one person worth crossing for?
