After leaving his hometown of Nazareth, Jesus made Capernaum, on the northern shore of the Sea of Galilee, the center of his ministry. The Gospels tell many stories of Jesus teaching and healing there.
Today, you can see the remains of a 4th-century synagogue, which stands on top of an earlier synagogue that is likely the one where Jesus preached. The remains of Peter’s House and the 5th-century church built around it can be viewed through the glass floor of the modern church built over the site. The tradition that the house belonged to Peter (the disciple of Jesus also known as Simon) goes back to the middle of the 1st century.
