Capernaum, on the northern shore of the Sea of Galilee, played a significant role in the ministry of Jesus. The town became the Galilean center for the ministry of Jesus.
And leaving Nazareth he went and lived in Capernaum by the sea, in the territory of Zebulun and Naphtali, (Matthew 4:13 ESV)
The aerial photo below was made on approach to Capernaum from the east. The site most visited by tourists may be seen left of the center of the photo. You may recognize the new church and the ruins of the synagogue. This property is owned by the Franciscans. To the right you will see the Greek Orthodox Church and the property they own. Evidence of some excavations may be seen.
There is not much remaining of ancient Capernaum. This is not surprising in light of the pronouncement of Jesus.
And you, Capernaum, will you be exalted to heaven? You will be brought down to Hades. For if the mighty works done in you had been done in Sodom, it would have remained until this day. (Matthew 11:23 ESV)
