On January 6th the Catholic Church celebrates in its Mass the Epiphany, which commemorates a triple manifestation of Christ:
(1) to the Magi - i.e. to the Gentiles;
(2) in His Baptism, when the Voice from Heaven declared, "This is my beloved Son;"
(3) in the miracle of changing water into wine at Cana.
Since the time of the Apostles, Christians in the Holy Land have marked the spots where these events took place. When they were able, the Christians built churches and other monuments at the locations. Even when war and various disasters leveled or ruined the structures, the Christians always built again on exact the same spot.
The structure on the right is a church,
of necessity made of wood (i.e. easily rebuilt) due to frequent flooding
