This is Capernaum which is on the Sea of Galilee. Jesus came to this area because Nazereth rejected Him. It is where He spent the most of His time ministering. He did most of His miracles here. It's where He called the disciples to be fisher's of men. This is the synogogue in Capernaum where Jesus taught.
It's hard to see but these are the remains of Capernaum. Up close we could see the way the homes were broken up into living areas.
The darker layer is the actual synagogue wall from the time of Jesus.
