St Peter in Gallicantu Church is on the way to a slope which continues from Zion gate out of a rampart in Jerusalem Old City. It is said that the church is built on the ruin of the high priest Caiaphas's residence. The Lord Jesus Christ was caught and spent over a night in this place before crucifyed. One of Apostles, Peter slipped into the court at the high priest Caiaphas's residence, and waited and saw about the Lord Jesus Christ, warming himself at the bonfire, in the night when the Lord Jesus Christ was caught. Peter however denied the Lord Jesus Christ for three times, when people beside him examined him closely, saying "you, too, were the pal of Jesus". At that time, the chicken just sang twice as the Lord Jesus Christ had predicted.
