St. Patricks Cathedral
I don't think you can order this set of
spirals stairs from a catalog. Some of the Catholic churches have the
most wonderful architecture in the world. St. Patrick's Cathedral is no
exception, looking at this set of stairs and walking up and down it
gives you a sense of awe.
Knowing how long it would take to construct a set of stairs gives you
even a deeper sense of admiration for the people who built it.
