In the 1870s the Sisters of Loretto built a chapel for the school they ran in Santa Fe, New Mexico. But the architect failed to include a staircase to the choir loft 20 feet above the floor. And then he died before he could rectify the situation. The sisters prayed a novena to St. Joseph to find a solution, and on the ninth day of the novena a mysterious carpenter showed up and offered to build them the perfect staircase for free. The accepted his offer. Months later he had completed a spiral staircase, and then he vanished, without leaving a trace of who he was or where he came from. The staircase he built defies explanation: it lacks a central newel post, standing only due to the strength of the two stringers. Those stringers are bent and twisted into helixes, which is a very difficult thing to do to wood. He also built it using no nails or glue, just wooden pegs hold it together. Also, the wood is some variety of spruce, but analysis reveals that it is a species of spruce unknown on earth. Some suggest that the carpenter was St. Joseph himself or an angel whom he sent to help the sisters in their need. Others say it was a highly skilled French carpenter who had moved into the area about that time. Either way, there is little doubt that there was some divine intervention in the construction of this wonderful staircase. The staircase still stands. it was in daily use until the school closed in 1968, and since then the chapel has been a privately held museum. It is among the most-visited tourist attractions in New Mexico, still inspiring awe and wonder in believers and non-believers alike.
