Holy Years are started with the opening of the Holy Door at the Cathedral, located in the Quintana Square. This happens on the 31st of December in a ritual that will be attended by thousands. The archbishop of Santiago knocks the wall that covers the Holy Door with a silver hammer. The wall will then be fully knocked down and removed to allow pilgrims to enter.
Once the door is open it will be available for pilgrims to enter through for just one year before being walled closed again!
