The first ward actually has a third floor with more classrooms, which I find unusual for a church building. It is accessed by two staircases. One is normal, and the other is this metal one:
It is so small that I felt cramped on it. It also looks out of place compared with the rest of the building. I have a suspicion that there was originally only one staircase up to the third floor, and this one was added for safety/fire code reasons.
On the third floor are a few classrooms and a much larger one that currently serves as the Young Women's room.
