Many other Eastern churches have gilded or painted domes, but these domes are genuine made-in-Homestead stainless steel. Saint Nicholas Orthodox Church has its own Wikipedia article. It is a Ruthenian, or Rusyn, or Carpatho-Russian congregation that belongs to the American Carpatho-Russian Orthodox Diocese, a group of Ruthenian churches that left the Roman Catholic Church because the American bishops refused to allow them to keep their Eastern Rite traditions, notably married clergy. (The problem was later addressed with a separate Ruthenian Greek Catholic hierarchy for North America—too late to prevent this particular split.) The building itself was begun in 1936, but, what with one thing and another, it was not completed until 1950.
It was a day of sun and clouds, so we have pictures in very different lighting.
