It was close to this stunning site (just north of the Sea of Galilee) that Jesus preached his Sermon on the Mount. Built in 1936-38, the Church of the Beatitudes is octagonal, representing the eight Beatitudes from the Sermon on the Mount. Although there is not specific evidence that this church is on the exact spot where Jesus preached the Sermon on the Mount, it's reasonable to assume it's near by.
Matthew 5:1-3, 9
Now when he saw the crowds, he went up on a mountainside and sat down. His disciples came to him, and he began to teach them saying: "Blessed are the poor in spirit, for theirs is the kingdom of heaven ... Blessed are the peacemakers, or they will be called sons of God." (NIV)
