This memorial cross made of light wood—dedicated to the memory of a deceased monk—is one of many that bikers encounter repeatedly along the way. They are all symbols of remembrance of the crucifixion, but also of the resurrection of Jesus Christ. + "With us on earth, His memory exists, 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, as we are still wanderers, journeying toward our fatherland." (Bernard of Clairvaux) Some passersby have placed stones at the foot of the small sacred monument.

Very interesting climb, with extreme percentages, it takes us to beautiful open plains that give a great view! Official pass referenced by the 100 passes club. Certainly an unmissable challenge if you are not passing far, and the most interesting in the nearby area.
