School architecture, Madeira

So, this is the roof of a school in Porto da Cruz, Madeira. The bit topped by the rust coloured disc is (I think) the top of a stairwell, and I'm guessing the purpose is to give access for the schoolchildren from their classrooms at sea level to the church which is behind me. Whatever the reason for such a gorgeous concoction of lines and curves - well done that architect.
