This basilica, built in 1924 over the ruins of more ancient churches, marks the traditional site of the transfiguration of Christ in the presence of Peter, James and John, along with the appearance of Moses and Elijah. There are depressions in the shape of two footprints in the rock. I'm not sure if this was the work of Jesus, or of some over-eager monks in an earlier age.
But Mt. Tabor is the spot. It's been attested to from the earliest days of the Church. It's an inspiring place to visit and a most peaceful place to pray.
