A nice legend surrounds this bridge!

Only the two stone beams form a cross in its simplest form, yet in a highly exposed location overlooking the bay that extends inland here. And of course, this small sacred monument—like all crosses encountered by hikers along the way—is an essential Christian symbol. It stands for the memory of his crucifixion, but at the same time also for the resurrection of Jesus Christ. The following quote comes from the important French order founder and doctor of the Church, Saint Bernard of Clairvaux: + "With us on earth there is His memory, but in the kingdom of heaven is His presence: This presence is the joy of those who have already attained salvation. The memory is our consolation, we who are still wanderers, traveling toward the Fatherland."
