A chapel was constructed somewhere in the 19th century. When it was ready, the nuns found that there was no staircase built to take them to the top level.
They spent 9 days praying to St. Joseph, who was a carpenter.
On the last day, a stranger knocked at their door and said that he was a carpenter who could help them build the staircase.
He constructed the staircase, all by himself, which was considered to be the pride of carpentery.
None knew how the staircase could stand by itself as it did not have a central support.
Then the carpenter, who did not use a single nail or glue to construct this staircase, disappeared without even waiting for his payment.
The second mystery is that the architects, engineers and scientists say that they cannot understand how this staircase can balance without any central support.
The third mystery is from where did the wood come? They have checked and found out that the type of wood used to build the staircase does not exist in the entire region.
There is another detail that has just increased the belief in the supposed miracle: The staircase has 33 steps, the age of Jesus Christ.
