The discovery of the Magdala synagogue occurred after the center, a Christian guesthouse in Jerusalem operated by the Legionaries of Christ, decided to build a hotel and visitor center near the Sea of Galilee. They chose to build in Magdala, said to be the home of Mary Magdalene, about 100 miles north of Jerusalem.That last comment is wild speculation, but it's nice to have the background to the discovery anyway.
Before the complex could be built, however, the government required that there be an archaeological investigation on the site. The dig, directed by Dina Avshalom-Gorni and Arfan Najar of the Israel Antiquities Authority, began in July 2009. One month later, workers uncovered the first remains of the synagogue.
Archaeologists have since unearthed pottery, coins and frescoes that have retained their vivid colors through the centuries. Magdala was one of several Galilean towns where Christians often shared the synagogues with Jews. The synagogue may have been destroyed during a Jewish revolt against Roman rule between 66 A.D. and 70 A.D.
In October 2009, [excavator] Avshalom-Gorni told CNN: “We are dealing with an exciting and unique find. This is the first time that a menorah decoration has been discovered from the days when the Second Temple was still standing.”
Since the discovery, the Israel Antiquities Authority has given the Notre Dame of Jerusalem Center permission to build the hotel and visitor center, with a projected opening date of July 2012. New construction plans add an ecumenical chapel on the spot where the ancient synagogue was found.
In addition to the synagogue’s historical significance to Jews, [Father Eamon] Kelly, [vice chargĂ© of the Pontifical Institute Notre Dame of Jerusalem Center] sees it as a possible moment of interfaith harmony, telling an Irish newspaper that “there is a high probability that the people from this synagogue were followers of Jesus and may have witnessed his miracles firsthand.”
A stone engraved with a seven-branched menorah was also found in the building.
