The Problem

In our pre-trip engineering project, the kids were introduced to the problem: have access to the second story balcony using minimal floor space. Seeing the Loretto Chapel in person, they noticed how small the space is and understood why alternative staircase models would not have worked as well.

Addition and Subtraction

When visiting historical sites, I find it fascinating that sometimes what you see is in the same original condition (like homes where curators have located the exact dishes the family used). It is also interesting how places change over time. We learned that the banister handrails were added afterwards so the nuns would no longer have to climb on their hands and knees, clinging desperately to the two full turns of the staircase. Sounds like a good move!

In discussing the lack of central support, the kids quickly pointed out that there are supports connecting the staircase to the building. These are not original and have actually weakened the structure of the staircase. Isn’t it interesting that as we try to preserve the past, we sometimes damage it along the way.

Why “Miraculous”?

There are a few reasons the staircase is considered miraculous. The way it was engineered without visible supports, the builder, and the type of wood all contribute to the mystery.

In our engineering project, there were several different models and materials attempted. The most effective model was created by Grandma with cardboard, a drill, a pipe cleaner and her Grandson’s running commentary.

If we hadn’t done the project, none of us would have had the same level of appreciation for the engineering of the actual staircase.
