Our Lady Of The Mount Roman Catholic Church. Warren, NJ. This parish is about to celebrate its 100th Anniversary. The vibe I got from the very polite caretakers was that they truly believe in what they do, both spiritually and in the physical care of this beautiful, unique and charming structure. The statue of Mary in the grotto is gentle from a distance, but a bit arresting up close due to the glass eyes set into her head. 13 August 2007.
