st. michael's, homestead

St. Michael's in Homestead Pennsylvania has been a structure I've looked at for years. It sits on the edge of the vast commercial development - The Waterfront. From the sea of parking lots, the figure at the top of the belltower was always an enigma. Catholic Churches are supposed to have crosses or The Virgin on their belltowers. This looked like neither.

Using a telescopic lense, I discovered that the figure was a carpenter. A statue made of cement that most common of mixtures. The figure must be Joseph the iconic carpenter. However, this icon is standing on top of three buckets pouring their contents onto a globe. Are these steel furnaces spilling their molten metal on to the known world? Is the figure a Homestead steel worker - a hunky - industrilizing the world? Is the figure the steel worker as deity?

The two side towers look like minarets. What are minarets doing on an Eastern European chuch in Homestead? Was the architect remembering the minarets he saw, as a young man, in Eastern Europe?
