When the restoration team began the work, it was noticed that the staircase leading to the chapel was missing its first step.
The work continued and a few months later, a team member found a stone with characteristics similar to the gap in the missing step and the stones that formed the other steps.
When taking the stone to the stairs, it fit perfectly into the gap, showing that it really belonged there.
Therefore, the staircase was restored and maintained as it was built.
